Fix for ATSC after uninstalling Rollup 2
In some cases you may find that ATSC (HDTV) no longer works after uninstalling Media Center Rollup 2 from your computer. The issue is caused by a schema change in the Tuners registry key. Today I identified a workaround to get your ATSC back up and running without reinstalling Symphony or Rollup 2.
To restore your ATSC functionality in Symphony:
- Stop all Media Center services and processes
- Close Media Center
- Start-->Run-->services.msc (or Control Panel-->Administrative Tools-->Services)
- Stop "Media Center Receiver Service"
- Stop "Media Center Scheduler Service"
- Open Registry Editor (Start-->Run-->regedit.exe)
- Delete the key at:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Media Center\Service\Video\Tuners - Start Media Center
This has not been rigorously tested, and has not been "officially" released to the Microsoft Knowledge Base yet. I am fairly confident of the fix, but this is posted AS-IS, with no warranties.
