Just a quick update.

I hooked up the PS3 (HDMI-DVI) through the 990 to my Sony 50A2000 (SXRD) last night and briefly watched the Dave Matthews and Tim Reynolds Blu Ray.

At first, I checked off all of the video resolutions in the PS3 setup and set it to automatically adjust the output resolution. This resulted in the DVD playing at 1080i. Then I deselected everything except 1080p, which, as expected, resulted in 1080p output.

Not sure why this happened - perhaps the native format of the show was 1080i?? I'm not really sure and didn't have too much time to play with it - set it up at 1AM.

I'll report back if I find anything meaningful. But 1080P shouldn't have been a problem for your situation, I don't believe...
