When remotely log in to the host PC and after choosing MY Movies part of WMC, I get a black screen. However I can navigate in all directions as I can see on the host but not on the remote PC. I'm not trying to stream a Movie simply select it to play on the host PC.
Any guidance in correcting this would be much appreciated.
In order to solve this problems you can:
1) Try to reduce hardware acceleration and/or desible overlay from server side.
2) Microsoft fixed this issue in Windows 8, so you could upgrade your OS if that is possible for you.
3) Some videoplayers could skip overlay and hardware acceleration, so you could change your videoplayer to avoid this issue.
