The MS dash and dvdx only supports 480p.

i patched the msdash.xbe and the default.xbe on dvdx2 directory. But I still don't see any difference when I watch DVDs. Any idea? I bought the video components too. I have a Sony 47" widescreen HDTV.

thanks

did you enable 480p in the dashboard?
It'll be under video.

And I guess since its just a hack you might not notice quality difference. I only use the hack cuz my PJ prefers a 480p signal.

yeah i did. I enabled all of them under video. *sigh* I guess I might have to shell out couple of hundreds to get a real progressive dvd player.

or maybe i'm expecting too much. My friend has a HDTV receiver and when we watch sports on ESPN, it picture is SUPER crisp. How is is playing 480p compare to watching a HDTV channel?

Dude. It should look better (i.e. you should see it) but come on, a DVD has less than 1/4 the resolution of HD ESPN, so obviously a DVD will never look even 25% as good as a 1080i HD broadcast.

Wrong, wrong, wrong! There are DVD players on the market that support 720p and 1080i, particularly Samsung. This means in all reality that Xbox might be able to support these formats only if programmers know how to utilize the .xbe to do this. I'm not a programmer so please don't flame me. I'm only speculating the possiblity of this support in the future.

Wrong! Wrong! Wrong!

Uh, that's great that there are DVD players that upconvert their image to 720p and 1080i.

But there is one problem with that. A DVD doesn't hold information at that resolution!!

A DVD stores data at 720x480. If you watch at a higher resolution, it's not like there is any more picture data there. Sure up-conversion routines can fill in the extra pixels and even guess as to what the missing pixels might have looked like, but only with the same data that is there, so it's still blurry and doesn't offer any more clarity. There is no real benefit to watching a DVD at higher than 480p. (note: 3:2 pulldown, etc. deals with frame rates and that's a whole 'nother thing.)

HDTV broadcasts images at 1920x1080. D-VHS records at 1920x1080. So you can see, a DVD will never even be 25% of what HDTV or a D-VHS VCR can do.

I guess I was wrong and I jumped to a conclusion that I should have known better about. Your right, all it these devices do is double up resolution.
