1080i Dvd Playback
« on: January 29, 2004, 05:54:00 AM »

Interesting, while i am not familiar with BenJermy's MXM dash, i'll definenltly look into it if i could get the original ms dvd playback to be in 720p.  Good find, can anyone else verify this?

Unless you did something to modify the actual code there are a few problems:

1) The reactor scene is in the bios - it loads before the dash and video settings are ever viewed.  The bios is always 480i.  Myself, Ngtshd, and others have found no way yet to change the bios to 480p no less 1080i.  I also have the 1080i option selected in my dashboard and I can verify that the output is still 480i for the bios (my television tells me extactly what signal it is receiving).

2) The Xbox dash is also always 480i.  It is totally independent of the video settings.  This causes tons of people with front projection and a few rear projection sets problems since they cannot view the dash through their component inputs (this is very very well documented and some elaborate workarounds are out there for it since they can only recieve 480p, 720p, 1080i).  If the dashboard could be altered by just changing the video settings this wouldn't be a problem and this is exactly why this group bitches like hell at MS.  The only way to change to dash is to hex edit (and thus it becomes unsigned requirig modchip).  So far - no one has been able to edit to to produce anything more than 480p.  Not that I'm an expert programmer but a 720p/1080i image would have to be coded specifically - the Xbox does not have scaling functionality for these resolutions.

So unless I've drastically misunderstood what you are saying, I can assure you that changing the video option in the dashboard has absolutely no effect on either the bios graphics nor the dashboard itself.  If there was something else you did, please let me know.

Ditto on what ChrisF said.

The closest fluke I have had with MXM was when I set the autolunch DVD function to on in the config and it would automatically play the DVD in 480p using the MS Dash. The odd part was that I had the dvdplayer in the config was set to xboxdash.xbe in the settings which was the 480i dash. My 480p patched dash was renamed to xboxdash480p.xbe. I figured it was just a fluke and MXM was picking up xboxdash480p.xbe by accident. I coudlnt replicate the problem after that day but maybe something to look into.

makes no sense since DVDs are not 1080i. I know you can run true 1080i stuff in Windows Media Center. But to run DVD in 1080i makes no sense to do!

Yes DVDs are natively 480p. But upscaling DVDs has become a big hot topic in the home theatre world. HTPC owners have sworn by upscaled images for years now. And now with more 'affordable' DVI based DVD Players out there that can upscale to 720p and 1080i, the debate is only fueld even more.

My brother and I did a side by side comprison with a regular old $100something Sony progressive scan DVD player and the Sammy DVD player w/DVI out (sorry I keep forgetting the model #) and to be honest, half of the DVDs we tested looked the same on the Sony at 480p and 720p/1080i. He actually kept the Sony DVD player for like 2 weeks testing movies on his own between the 2 models because he wasnt able to see the big difference right away with lots of his DVDs. But on the flip side, there were several other movies though where we were defintely able to tell the upscaled image looked better than 480p/i.  The screen was filled more in certain movies and the detail was just sweet!

For upscaling DVDs - I'm convinced it's the source material.  Garbage in - garbage out.  You can scale shit all you want but if it's a poorly produced DVD you still end up with high resolution shit.  Like Monday Night Football in HD vs. some upscaled movie from a crappy source.  Yeah - it's all 1080i, but man Monday Night Football is incredible.
