You shouldn't have had to patch Evox - it supports 480p.
It doesn't matter if DVDs work or not - you won't have 480p DVD playback unless you have done some manual modification to the Xbox dash. You are seeing an interlaced signal. Same with the Xbox dash.
All my games are 480p off the harddrive - no issues. I've actually never heard of this issue but I guess from above it's been mentioned before. Maybe play with your other video settings - widescreen/normal/letterbox and see what happens to the games that aren't working.
I have a question - how do you know that the signal being received is 480p and not 480i? My tv shows me the resolution when I change sources. I'm just skeptical since you stated 480p dvd playback - I doubt you hex edited the ms dash and didn't mention it so I'm wondering how you are determining a 480i or 480p signal.
I copied my ini file below (note that I maintain a patched xboxdash.xbe that does support 480p - pxboxdash.xbe is the name). I left out the bios section but all in all fairly standard stuff and no weird settings. If I were you I'd start with a clean Evox and don't attempt to patch it as it doesn't need it if you have your settings in the MSdash correct.
