Hello mayostudent
Video (or composit) has the lowest grade of quality.
Then there is S-video, and the best is Component Y/G,Pb/B,Pr/R.
Y/G,Pb/B,Pr/R is in fact Y,Pb, Pr or R,G,B.
RGB is better than YPbPr.
This is because YPbPr has to be decoded first to RGB.
I do not know what DTV is. I think its digital TV and that is the very best.
In short from "bad to "best"
Video (or composite)
S-video
YPbPr
RGB
DTV
DVI is a analog/digital interface for flatscreen monitors.
I do not know any hardware with a DTV or Y/G,Pb/B,Pr/R output.
Mostly on videocards you have a composite or S-video output.
In my opinion, these cards do not have the quality as a normal pc screen.
If they work you always have to fiddle around with software to get rid of the black borders around your picture on a TV.
I use the Hollywood+ MPEG2 card to watch dvd?s in iso format from my server on my tv in dvd quality with all the menu?s and dolby digital/DTS sound.
It eats a lot of space on my server, about 4 to 8 Gb a dvd, but I?ve got room for about 20 dvd?s.
