That's the thing, the TV specs only indicate that it is 1080i, 480p or 480i...it doesn't state anywhere that it downsamples or anything. Maybe it was the CCC drivers used at the time with the 9500pro, but when I tried a 1080 res before, I had over-sampling, so I downed the res to 1366x768, and that seemed to display fine (using Bud's Redeux WS skin back then). Using the HD2600, along with the 8.3 CCC drivers, the RPTV is connected via DVI-HDMI cable (same way I was connecting before), the drivers automatically setup the cards res to 1920x1080 and I didn't have to do any adjustments in the CCC drivers what-so-ever. I only had to play around with them to setup a second monitor, which I was using to tweak some other things, but now I'm only using the RPTV.
Also, last night after setting up ffdshow properly to upscale DVD to 1920x1080, all I can say is WOW!!! I'm loving this more and more.
I have to tear myself away from playing, so I can update my googlepages with pictures and video.
