Guys, I need your help.

Having recently switched from Win7-64 RTM to the Retail version of Win7-64, I'm now having problems getting the Hauppauge HVR2200 to find the channels it was happily using a few weeks ago.

I've tried about every driver I can find for the 2200, and every combination of remove and reinstall the device I can think of. The same hardware was running fine under the release to manufacture version of Win7, the retail version is what is killing me here. I must have missed something obvious in my quest to get things working yet when performing a 'TV Channel Scan' I consistently get 'No channels were found. Make sure your TV equipment is properly connected to the computer' (it is, and it's the same setup as previously working)

WAF* is eroding fast so please, hit me with your ideas on how to make Media Center find my Freeview channels under Windows 7 Ultimate, 64-bit...

Cheers,

Rob

Great - thanks, I think I've tried that one, but no harm in running HWClear and trying again :)

--- Edit ---

Okay, it wasn't the driver - uninstalled via HCWClear, rebooted, reinstalled manually via Device manager, rebooted - setup the tuners - and still 'No Channels Found'

BUT - Then I found and tried this:
http://www.hack7mc.com/2009/09/clearing-guide-data-and-tuner-setup-from-windows-7-media-center.html

which *worked* ! :) - Essentially, it appears that the tuner / guide database was corrupted/sutffed/whatever and so, deleting it and re-running from scratch worked (YAY!)

In the interests of replication should the above link stop working, there are two ways to delete the database and start from scratch.

The Long Way
1) Quit Media Center
2) Start 'Task Manager', Click the 'Services' tab and click the 'Processes' button
3) Stop the 'Windows Media Center Receiver' and 'Windows Media Center Scheduler' services
4) Switch back to 'Task Manager' and open the 'Processes' tab.
4a) Stop the eh*.exe processes
4b) Stop the mcGlidHost.exe process
5) Open explorer, and navigate to "C:\ProgramData\Microsoft\ehome" (it's a sneaky hidden directory)
6) Delete the file mcepgX-X-X.db (where X-X-X is some kind of version)
7) Delete the directory mcepgX-X-X
8) Reboot
9) Cross everything that can be crossed, make sure the moon is in the right part of it's orbit, chant the right incantations and restart Media Center - you'll be starting your TV tuning from scratch now... good luck.

The Short Way
1) Quit Media Center
2) Open Task Scheduler -> Microsoft -> Windows -> Media Centre.
3) Manually run the MCERecoveryTask
Or
2) Open an elevated command prompt
3) run "mcupdate -MediaCenterRecoveryTask"

I can't confirm the short way, but it's far less painful so perhaps someone with a similar problem can try that first and post their findings...
