Windows 7: WMC Live TV reverts to menu daily - 16x9 resolution drops to 4x3

WMC Live TV reverts to menu daily - 16x9 resolution drops to 4x3

I have two HTPCs built on Shuttle SH67H3's, with SSDs, 4GB memory, Intel i3-2100T processors and Windows 7 Home Premium. The only real difference is one has a video card with S-Video out because itís on an older TV (Living Room), while the other is just using the on-board HDMI (bedroom).

Every evening when I turn on our bedroom TV, WMC is still running, but it is back at the initial start menu (recorded tv, guide, live tv, etc.). The night before it had been left on Live TV. Iíve checked it a couple of times in the morning, and itís still on Live TV, so this appears to happen sometime during the day. Iíve never had this happen on the other HTPC (the one using S-Video), it always remains on Live TV. Iíve checked the Windows runtime, and itís been days since the last reboot, so I know itís not rebooting nightly (or daily).

In an attempt to resolve this, I did a complete reinstall of Windows 7. It didnít resolve the Live TV problem, but now WMC will sometimes drop from 16x9 resolution to 4x3 resolution. It did it last night when I paused Live TV for a minute Ė I came back in the room and the paused image had black bars on all four sides. The only way I can get it back to 16x9 is to shutdown WMC and restart it.

Does anyone have any ideas as to what is going on? Both the HDMI and S-Video cables are plugged into receivers, and both the receivers and TVs are turned off when they arenít in use. Thanks for your help!
