Xbox 360 not playing MP4 video or OGG audio

I have set everything to standard Xbox 360 profile, but MP4 video doesn't play and the same goes for OGG. Just keep getting the ol' "file format may not be supported message" from the Xbox. MKVs and AVIs work perfectly based on the ones I have tried.
I then edited the Xbox 360 profile in profiles.xml:
1. OGG is in the transcode list but its not working.
2. tried adding MP4 to the video transcode list, but its still not working.
3. add the ogg mediaformatprofile to xbox 360 and it still did not work.
So far this works much better than PS3 Media Server (which I also could not get OGG transcode to work but managed to get MP4s to work), but I really need to get OGG transcode to work since thats what all my music is in. As for the MP4s I will convert them (if I can find software that actually works) if all else fails.
any ideas to get these to work???
