Miscellaneous Update Rollup 2 issues and how to work around them

Miscellaneous Update Rollup 2 issues and how to work around them

  • Comments 20

I wanted to list a few miscellaneous issues that have been found recently with Update Rollup 2 for Media Center 2005 and describe how to workaround them.  Some of these have already been described individually elsewhere, but I wanted to make it more likely that they are found in search engines by posting them again.

1.  DVB radio tuning causes a blue No TV Signal overlay

Peter Rosser described this issue and workaround in more detail in this blog post.  He lists the registry value that needs to be changed to workaround this problem until it is released in a future Media Center rollup package.  As a convenience, here is a command line that you can run to update this registry value do you do not have to use regedit:

  1. Click on the Start menu, choose Run and type cmd
  2. Run reg add "HKLM\Software\Microsoft\Windows\CurrentVersion\Media Center\Service\Video\Tuners\DVR" /v NearUnderflowCheckMillis /t REG_DWORD /d 4000 /f

Note: You can copy and paste this command into the cmd prompt by highlighting it in this blog post, pressing Ctrl + C, then right-clicking on the cmd prompt window and choosing Paste.  Make sure that you copy the entire command as it is listed above, including the space between Media and Center, and do not add any extra carriage returns in the middle of the command line or it will not work correctly.

2.  High-definition (ATSC) tuners stop working after uninstalling Update Rollup 2

Peter Rosser also described this issue in his blog, and you can find more information in this post.  Here is a set of steps that will delete the registry value that is needed to restore ATSC tuner functionality if you uninstall Update Rollup 2:

  1. Close Media Center
  2. Click on the Start menu, choose Run and type cmd
  3. Run net stop ehsched and net stop ehrecvr
  4. Run reg delete "HKLM\Software\Microsoft\Windows\CurrentVersion\Media Center\Service\Video\Tuners" /f
  5. Restart Media Center

Note: Like in the issue described above, you can copy and paste this command into the cmd prompt by highlighting it in this blog post, pressing Ctrl + C, then right-clicking on the cmd prompt window and choosing Paste.  Make sure that you copy the entire command as it is listed above, including the space between Media and Center, and do not add any extra carriage returns in the middle of the command line or it will not work correctly.

3.  Media Center will not correctly enter standby mode if the TV tuner was used prior to going into standby

This is a recently discovered regression introduced in Update Rollup 2 that we are currently working on a fix for.  Once a fix is ready, it will likely be included in the next Media Center hotfix rollup package.  The only known workaround at this time is to disable Media Center sounds by navigating to Settings | General | Visual and Sound Effects and unchecking the box labeled Play sounds while navigating Media Center.

4.  ATSC minor channels are listed incorrectly in the Media Center television guide

Peter Rosser described this issue in his blog in this post.  This is a known issue that will be fixed in the next hotfix rollup for Media Center 2005, but unfortunately there is not a way to workaround this issue in the meantime.

 

  • After the roll-up I cannot play dvd movies,the media center goe's blue and freezes
    there is now yay out but to restart.
    I get an error message that says
    Application Failure
    A critical Media Center process has failed. Please restart the computer and try again. if the problem persists,contact your hardware manufacturer for assistance.where can I get help I built this unit myself.
  • Hi Gordon - The workaround listed at http://blogs.msdn.com/astebner/archive/2006/02/17/534559.aspx might help solve the application failure issue that you're seeing, so I would suggest trying that out and seeing if that helps here.

    I would also suggest trying to update drivers to see if that helps solve the bluescreen that you are describing.  You might find information in the application or system event logs on your computer to help narrow down the cause of that issue.
  • Hi.

    I recently installed rollup2 (complete fresh install) and i have some sound issues.

    Here in Australia, ABC2 and Channel Seven dont transmit in AC3 sound, so when i record or playback recordings from these channels, all is fine.

    The problem is the channels that DO transmit in AC3 - thats 10, 9, ABC and SBS. If i pause live tv, "rewind", or even change channel, i lose ALL sound. I have to then stop the recording or playback, then start again to return the sound.

    I SUSPECT this is a decoding issue, however i am running the same software and setup as before RU2.

    Recordings made PRIOR to RU2 all work fine, regardless of which channel they came from.

    Any hints?
    Thank you for any help.
  • oooops - sorry, i was in a rush and forgot to mention my specs.... i'm using an mce box with the latest updates, 2 aver media digital tuners, nvida decoder, standard latest drivers for on board sound card, all running into a yamaha receiver via an audio coax... thanks again for any imput....
