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:

1. Stop all Media Center services and processes
   1. Close Media Center
   2. Start-->Run-->services.msc (or Control Panel-->Administrative Tools-->Services)
   3. Stop "Media Center Receiver Service"
   4. Stop "Media Center Scheduler Service"
2. Open Registry Editor (Start-->Run-->regedit.exe)
3. Delete the key at:
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Media Center\Service\Video\Tuners
4. 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.

  I feel like I've dropped into a Lewis Carroll world on all this - and all because I bought a HDTV from BestBuy! Normal punters just get the STB and plug to their TV - oblivious.
  
  Since I'd already been using my HP MCE PC with cable - I just assumed it would all work with HDTV!
  
  I have found this card: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=8757506527
  
  And this seems very promising. Seems like I can probably push the QAM signal out of the STB into this card... or even the digital signal directly...
  
  However - still waiting for Comcast to tell me if their HDTV over analogue is QAM and not encrypted...
  
  Is that the Cheshire Cat I see grinning at me?!
