I also posted this in the audio section because I simply don't know if this is an issue with m receiver or my video card.
When running HDMI from my windows 7 media center (1gb ATI 5450 card) to my SR508, the video appears normal until I launch media center. The screen blanks for a brief moment, then media center loads. About 10-15 seconds later, media center crashes with an error message stating that color depth must be 32 bit. I've checked before and after the crash, and the color depth is 32bit. If I bypass the receiver and plug directly into my TV, it works flawlessly.
