You know how it goes though, everything starts snappy and responsive and then months later you’re wondering exactly what plug-in you installed that made everything seemingly slow down. So you check your overall system health and then disable or uninstall all the plug-ins that might be to blame. But then what? If none of that works, how do you restore your system to its original glory without punting on 1st down (re-installing Windows)?

Luckily Windows 7 Media Center is pretty easy to reset and get back to where you were — sans the bad parts. This won’t take you an hour and the hardest part is setting up your custom guide settings. The best part is your scheduled recordings can be restored easily.

One last thing before we get started. Use at your own risk! This worked for me, but might not for you.

Start by stopping all the Media Center services like
Media Extender Service and Windows Media Center Receiver Service.

Then open task manager and kill all the processes that start with eh.

Now you should be able to move all the content of the hidden folder C:\ProgramData\Microsoft\eHome\ to a safe place. (you’ll need the contents later to restore your scheduled recordings. You can use mcBackup to ensure you have the files you need, but the eHome directory still needs to be empty to reset Media Center.)

Reboot (you might be able to start the services here, didn’t try).

Launch Media Center and re-run live tv setup. After all your tuners are configured, setup your custom channel lineup manually.

After you have the guide the way you like it, dig into the eHome files you moved and sort by date finding the newest mcepg*-* folder. Inside there you’ll find a backup folder and in there a recordings directory. Sorting that folder by date will reveal the newest backup. (If the time stamp got reset you can look at the name which is year,month,day_hour,seconds).

Now open a cmd prompt and run this command replacing the location of your backup file. Or restore your recordings with mcBackup.

“C:\Windows\ehome\loadmxf.exe –i C:\Users\MC\Documents\eHome\mcepg2-3\backup\recordings\20100529_091633”

Finally launch Media Center and go to Settings>TV>Guide>Get Latest Guide Listings
A dialog will let you know they’re downloading and later another when the download is complete. Now go to Scheduled Recordings all your shows should be listed.

This worked perfectly for me and documenting the process took longer than the process itself. Best of all most of my Media Center settings were intact as well as all my plugins I wanted to keep. And my guide loads quickly, an undeleteable Recordings is gone and Media Center doesn’t take forever to launch anymore.

On a personal note, sorry for such long periods between posts. It isn’t that I’ve been really busy as much as that I’ve been preoccupied with personal things that I haven’t shared — like the fact that I’m trying to become debt free which means I don’t have any new gadgets to write about and the fact that I’m four months through six months of physical therapy after having knee surgery.

The bottom line is that I love me some football in HD, so I can’t ever see myself going without cable year round, and with the hassle involved in canceling and signing back up, the $327 a year ($62 for 7 months minus $110 savings for signing a contract) I’d save just isn’t worth it — not to mention I plan to expense the majority of the cost to offset my blogging income. I suspect for many it just isn’t worth it either. Sure there is lots of content out there available via other legal means, but the bottom line is that when it comes down to it, cable really isn’t that bad of a deal considering all the HD viewing options you get for the price.

Since the Jasper model looks identical to the older 360 you have to know what to look for to tell you have/are buying one. There are a few ways to identify it, but the most dependable is to look at the power requirements, which are printed on the serial number sticker on the back. While the older models required 14.2 amps, the Jasper only draws 12.1 amps. Now the great news is that you can actually see this sticker without opening the box by looking through the hole for the barcode sticker.

First look through this hole.

This is a falcon, notice it is labeled 14.2 amps.

This is the Jasper, it is labeled 12.1 amps.

These pictures were from an older Engadget post.

According to my kill-a-watt, the Jasper 360 only uses 90 watts while in Media Center mode, while the Falcon uses about 108. It is noticeably quieter than the Falcon as well, but still not silent enough to be in my home theater. The PSU makes some of the noise and the Jasper will work with the older PSU or a newer one (the newer one won’t work on the Falcon). Not sure if there is any way to tell which PSU is included when you buy it, but the one I bought had the older style PSU.

I’ll be honest. Part of the reason I wrote this was because I went looking for this information today and couldn’t easily find it via Google. So I figured I’d Google juice the title and drive traffic while at the same time help those in need find this information. And besides, it’s been way to long since I wrote anything here.

First download md5sum.exe and grab the MD5 hash from Microsoft’s site. To save you the trouble I’ll post the x86 hash here, but you should always get it when you are downloading a file. 8867C13330F56A93944BCD46DCD73590

Now simply call md5sum from the command line using just the iso as an argument, and after a few minutes it should spit out the same hash. 

Pretty easy huh?

One of the key add-ins in my household is one that adds the ability to control Media Center and extenders via my Home Automation controller since even the basic operations in my home are dependent on it. I can’t even watch Live TV in my house if this doesn’t work, so I needed a solution. Autonomic homes has supported Windows 7 since beta, but I’m not willing to pay $800 just for this one feature, so I needed the open source project that was free to work, the same one that I was using with Vista.

The now poorly named VMCController is a background MC add-in that features a few control ports so I can fully control any extender in my house via TCP. To get it working on Windows 7, I had to download and install the latest version as normal, but when I launched MC, I got an error about the add-in failing to load. So with some help from Olddog at the projects codeplex discussion page, I was able to get it working. You’ll need to download Olddog’s updated DLLs. But in order to replace the DLLs, first thing you need to do is to delete the HKEY_LOCAL_MACHINE\Software\Classes\Installer\Assemblies\Global\Default registry key as per this MS KB article — always backup the registry before editing by righting clicking on the parent object and choosing export. Now reboot and open Windows Explorer to C:\Windows\Assembly. Find VmcController.Add-In, then right click on it and select uninstall. Now copy the new VmcController.Add-In.dll from the OldDog’s zip file to C:\Windows\eHome and all the DLLs to C:\program files\Media Center Network Controller\ and finally start Media Center and test by telneting to localhost port 40500.

The only problem I’m having is that a few of the buttons don’t work, but I found work arounds. So instead of using button-skipfwd I used the command playrate skipforward, which does the same thing.

Hopefully the main contributer to the project will update the source with OldDog’s changes so that we can just run the installer like the old days, but at least it is working.

One of the commenters on the Engadget HD Podcast recently asked me to do this so here goes. It’s been over two years since I did a post like this and I have to say I’m amazed at how much of my equipment is the same and at the same time, how much is different.

The main uses from my perspective is to make various video files Media Center compatible, but since MPG and AC3 are pretty much the most standard codecs in the industry, there are plenty of other uses. Both of them require the latest version of DVRMSToolBox, written by my good from Andy. In fact it is what makes the entire process automatic. For both profiles, the DTB temp directory is used to create the files and then the final file is moved back to the location of the original file (in the case of the MKV AC3 files, the name is changed for obvious reasons). Until I release the rest of my process, you can create a simple “process conditioner” to automatically convert these files, or you can run them on demand with DVRMStoMPEGGUI (or queue them up manually).

The first is a very simple VOB to MPG converter. All it does is use ffmpeg to repackage the MPG and AC3 streams into an MPG container. The best way to create a vob to convert is to use something like DVDShrink to rip only the main feature and the main AC3 audio to a single vob. You can use DTS, but as you might know, in the case of Media Center DTS is not supported nativly and thus doesn’t work on extenders. To use this drop “Convert vob into mpg – ffmpeg.dpc” into “C:\Program Files\DVRMSToolbox\Profiles” and put ffmpeg.conf into “C:\Program Files\DVRMSToolbox\Applications\ConvertFfmpeg”

The second one was actually very difficult to get right and I’d still like to do some more testing. What it does is extract a DTS stream from an MKV file, then convert it to AC3 with eac3to, then finally remuxes it back to an MKV with AC3. It only retains the original video and audio streams and in fact doesn’t touch the video stream. To use it you’ll need to download eac3to and MKVtoolnix (both free). First extract the eac3to archive to “C:\Program Files\DVRMSToolbox\Applications\eac3to” and install MKVtoolnix with the isntall path of “C:\Program Files\DVRMSToolbox\Applications\MKVtoolnix\” And of course you’ll have to copy the “Convert MKV with DTS to MKV with AC3.dpc” to “C:\Program Files\DVRMSToolbox\Profiles”

Please let me know if these work for you or not, I’m really hoping to get these throughly tested before my final project is complete.

**Update** Already had to update the DTS to AC3 profile, this one should work better. Thanks Rich. 

**UPdate2** Had to update it once again because the AC3 bit rate was too high for dvr-ms files, it is now set to 448 instead of 640.

I’ve loved my HDHomeRun for as long as the product has been on the market, but never really used it heavily until I switched to Media Center about a year ago. Well ever since, from time to time I’ve experienced network issues that have caused less than perfect picture quality — drop outs, blocking, breakups etc. I’ve spent countless hours troubleshooting this and most of the time it ended up being the driver for my Intel 82566DC-2 network adapter. At one point I even spent some money to replace my switch since the NIC refused to auto-negotiate to 100/full with the 16 port Netgear switch I was using. Well for whatever reason the issues came back over the weekend and I finally threw in the towel and did what I should’ve done a long time a go.

The simple solution
I went down to CompUSA — yes they still have them in Tampa — and picked up a $14 NIC. I threw it into a spare PCI slot (you can use a USB NIC if you want) and plugged the HDHR directly into it. The cool thing is that I didn’t even need a crossover cable, in fact all I had to do was rerun the HDHR setup utility to rediscover the location of the device. And thanks to the beauty of APIPA — you know that 169.254.x.x address — I didn’t even have to set an IP on the NIC or configure an IP for the HDHR. 

Now my picture quality is back to the perfect and my only regret is that I didn’t just break down and do this earlier. So if you are having problems with your HDHomeRun, I wouldn’t hesitate to throw an extra NIC in your PC and at the very least isolate the problem.

**UPDATE**

Ian was very responsive to my concerns and has pulled the post — but yet the link still works. Never the less,  the original author has added credit to his post on his blog, but in a way that seems half-hearted to me. But perhaps that is because the intent of his comment was lost in the British to American translation.

Either way because this didn’t fix the problem I’m going to have to move the 360 into my closet. This isn’t a big deal since I don’t change games much anyways and have a Blu-ray player for movies, but it is disappointing.
