I have a working settings using cabac, deblocking, and trellis=2 at 720x480. Dropping the bitrate down to 400 allows the xbox to handle every advanced feature, and the quality is amazing for the file size (550MB for a 155 minute movie). I've only done a few test encodes and full length movie so far, the quality is just as good as a scene released xvid (700mb) but the file size is small.
I wouldn't say these are the best settings ever but I wanted to see what you could do with x264 and the xbox cpu. I have to say I'm impressed. Here are a few screens. You can see the cpu usage in a couple, I only had one scene with a small amount of stutturing and the dropped frames were mostly caused by taking the screens in xbmc. Without taking screens I had 32 dropped frames through the whole film.
And here are the settings I used for the encode.

Let me know what you guys think of these settings.
