Media Center Crashes when accessing Recorded TV on different PC

I'm running Windows 7 Ulitmate and every time I access recorded TV content in Windows Media center it (ehshell.exe) crashes. Specifically, it crashes when you select a program and go in the program details (by clicking on it).

This only happens if the content is shared is is on another PC. I have a small network with three (3) Windows 7 machines. The two others are Pro, the one with the issue is ultimate. The other PC's have no issue accessing recorded TV content on other computers. Using Homegroup to share content.

I've tried reinstalling Media Center with the same results. Here is the Event viewer content with Media Center crash info:

You may want to reinstall Windows Media Center, here is the step:


Reset Windows Media Center


1. Open Control Panel/Programs and Features.

2. Click "Turn Windows features on or off" in the left pane.

3. Expand "Media Features", uncheck "Windows Media Player". Click "Yes" to continue, and click OK to quit. Then Restart.


Note: If you turn off WMP, Windows Media Center will be turned off either. You may need to re-configure settings for Windows Media Center after re-enabling it.


4. Open "Turn Windows features on or off" again. Turn on the features "Windows Media Player" and "Windows Media Center". Restart.

Thanks for the quick reply.

I tried the steps above and the same issue persists. In fact, reinstalling seemed to retain all my settings.

The crash occurs on right when you click on the content - see attached. The remote computer (LAN) is called mediacenter1.
Here is something else I ran across in my searches:

Since Windows Media Center works from the .NET Framework, they
uninstalled .net framework 1.1 completely (via Add/Remove Programs), then
run Aaron Stebner's .net Framework cleanup tool
and then reinstall the .net framework 1.1 and all the service packs.

Someone else recommended that creating a new user account (not deleting the old one) fixed it for them.

Their comments:

I found the problem with MS technical support yesterday.

The issue was over permissions for the user. The account was computer
administrator (as created in in MCE), but somehow the permissions for the
user were screwed. The problem became evident when we tried to rename the ehshell.exe as part of the diagnostic
process - I did not have permissions to do this which was strange - refused to let me grant full control over files in the folder. The solution was to create a new user. MC worked straight away when I logged in with the new account.

I created another user account to test and got the same error. The user account was a full admin.

Add/remove programs has no entries for .NET 1.1. Only .NET 4 was present. Regardless, I ran Aaron's tool to remove 1.0 and 1.1 in case there were any remnants present.

Same error persists.

The timing is just odd, though. You click on the program, the detail displays, the thumbnail displays, then it crashed. It's about three seconds after the click.

Hopefully you have something else to try - thanks!
Did you get .NET Framework 1.1 plus updates from Microsoft and install? I work for a software company and have seen that many products require the exact version to operate, i.e. .NET 4 may not work with it.

DL'd and installed .NET 1.1 and then SP1. Rebooted and same issue.

I justed tested Internet TV - works fine. Also tested watching video's from the same shared computer and it works great. It's something about that recorded TV content. Maybe somethign when it's getting the thumbnail or other info?

Also tested copying the recorded TV content which worked, but defeats the purpose.

Just for kicks, I disabled my virus protection and it is working! Unreal. No messages or logs are anywhere to be found to say that Trend may be interfering, but as soon as it is disabled, no issues.

We use Trend Micro, specifically the version on the screenshot below. We use the corporate version which is the Trend Micro Worry-Free Business Security - Advanced 6.0 (WFBS 6.0 with Service Pack 3).

Hopefully, if there is anyone out there this can save them some time. Trend Micro and Windows Media Center don't mix.
