What?
DVD's are MPEG2 @ 720 pixels wide.
The only way that it is possible to watch a DVD on a computer NOT in progressive scan is to set your CRT monitor to an interlaced mode.
In short:

I too wonder about this. Also, can computers upconvert signals to 720p?
YES. All computers that play DVD's can scale the videos to anything they want,

Special card is needed for normal prog scan, there are some DVD players that have it, I believe.
NO. All computers that play DVD's already have what's necessary to decode MPEG2 at 720p, p in 720p meaning progressive scan.
Edit: Turn's out DVD's are 720 pixels wide, so it's not 720p.
Here: Anything having to do with TV's like "progressive scan" and "720p" and "up/down covert" don't apply to playing DVD's on a computer.
If I have the resolution set on my computer to 2048x1536, and I play a "fullscreen" DVD, in fullscreen on my computer, thats "up converting" a 720*X to 2048x1536.
When a DVD is "up converted" to 720p, there is no extra detail that you wouldn't see on a computer. It's just being scaled to fit your HDTV.
When playing a DVD on the computer, it's the same as just watching an AVI or MPEG file. There is nothing analog about it. DVD's just have files on them, .vob files...
