Simple question that I can't seem to get an answer on. Are the DVD-ROM drives in PC's progressive dvd players? Surly it matters by model, but I can't find any info either way. (I assume they are given a PC's resolution capability, but I don't know for sure.) The reason I ask is because I am planning on using a PC as a DVD-player in my HT setup and plan to use the DVI output on my video card. However, if the picture is not going to be at 480P I would just buy a seperate DVD player. Thanks for any help.
