Is there a FAQ on this? I was about to buy a Panasonic RP91 DVD player until I started looking into building an HTPC. I already have a Radeon 8500 and can get the DVI -> Component adaptor for it. I could then run output from the HTPC into my TV. I am considering getting a Toshiba HDTV, and one of the few flaws with the Toshiba is that it upscales all 480 line input to 540. This tends to yield some artifacts. So I got to thinking that using an HTPC to do the scaling and sending the input as 540p directly into the Toshiba would probably yield a better quality image rather than relying on the TV to do the upscaling. Same goes for 480i and 720p inputs. Are HTPC-based DVD players capable of doing 3:2 pulldown, etc? And what sound cards use toslink type digital optical outputs for DVD audio? I have a soundblaster live platinum 5.1 and I don't think it has a toslink out - just some proprietary spdif connector in the back. I haven't looked at the livedrive that closely, though. Even though the card can decode dolby digital I would rather output the raw audio from the DVD into my receiver and let it do the decoding..
