I am setting up an HTPC to use on a Sony 1272 PJ. I installed an ATI Radeon 7500 All-In-Wonder card and a 16X DVD rom. When playing a DVD from my DVD player which is hookep up to an AV receiver, the image was noticably better than what I was getting from the computer DVD rom. Is it because I have not set up the HTPC properly? Perhaps I should not use the DVD rom, as the picture quality pales in comparison to the regular DVD player being run from the receiver. I do not want to miss out on obtaining the best possible results from HTPC so I am assuming that I need to do some more adjustments in the HTPC set up. Any practical tips on how?
