I also have a Shuttle SN78SH. Whenever I wake my PC back from sleep my WMC7 and WMP12 are unusable. Media Player refuses to play any video, while media center is very, very, very slow. For example it takes 1 min for the highlight to change its position.
I rather assume that this is a Windows 7 power management bug, which occurs with specific hardware. I tested with a clean installation of Windows Vista and there waking up from sleep does not have any problems. While a clean installation of Windows 7 I experience serious problems:
1. Windows 7 Ultimate x32 (with x64 tested too, same result) clean install + original mother board drivers
(as they came with the Shuttle PC on a CD) -> wmp12 and wmc7 unstable after waking from sleep
2. Windows Vista Ultimate x32 clean install + original mother board drivers (as they came with the Shuttle PC on a CD) -> everything works perfect after waking from sleep
Initially I thought that some hardware device is causing the problem or even BIOS. But my last test rather points out a possible windows 7 bug.
Do you have any new information? Thanks

I also tried to update all my device drivers for Windows 7 from here: http://global.shuttle.com/download03.jsp?PI=939&OS=8 but still no success.
