Hi I've recently installed Windows 7 on my HTPC and setup Media Center (WMC) and it seems to be working well after a fresh boot but, when the computer wakes from sleep and I try to play live or recorded TV I get "Files needed to display video are not installed or are not working correctly. Restart Windows Media Center or restart computer." Restarting WMC doesn't help so the computer needs to be rebooted in order to get it to work. This isn't really an acceptable solution. I've read some things online that adjusting the sound setting will fix this but I've tried every combination (stereo, 5.1, 7.1 in WMC & stereo in the HDMI driver) and it still doesn't work. I'd appreciate any help anyone could provide. Thanks.

Since you mention TV the problem may be your TV tuner. Go to control panel > device manager and locate the TV tuner. See if there is a Power Management tab on the TV tuner properties and if so, then uncheck the box that allows it to sleep.
I have an HDHomeRun and I can't see anything in the Config GUI about sleep.

I'm not sure we are talking about the same things, were you in Control Panel > Device Manager looking at the properties for the HDHomeRun card or were you in some configuration settings window for the HDHomeRun?
I don't have a TVTuner card installed so I can't check to see if they have the option but what I was referring to is a Power Management Tab similar to what I see here on the network card:
I would also suggest you make sure you have the latest BIOS for your computer/motherboard because ACPI (which controls sleep) was commonly updated in the BIOS to support Windows 7.

1) I meant the latter but tried the former based on your suggestion here. No joy, unfortunately.
2) I've looked into this and my BIOS is two versions behind although the last one says it's a Beta version (but from 2010). Anyway, I'm waiting for some new RAM and a new CPU to arrive, so I'll wait and do it all at the same time. I'll report back when all is said and done.
Cheers.

In other words, they know it happens but "it's not their problem"

Having the latest drivers is usually best and since they specifically made mention of it I do think you should update the HDMI driver if one is available. When you boot up, things happen in a certain order, but if some devices sleep and others don't it is quite possible links may be broken. A new driver could change the way things occur on wake. Like they said "disable HDMI audio output. If the error no longer appears, this confirms that the issue is with HDMI audio".
