I have fuppes successfully set up and streaming to my xbox 360. Fuppes works great with the mp4 videos I've been creating, and recently I've been experimenting with creating mp4s with multiple audio channels (such as the default English track and the commentary track). This works great with my daapd/iTunes server, but the 360 chokes on any track with more than one audio channel. This appears to be a limitation of the xbox 360 itself.

Is it possible to transcode to another format while removing/disabling all but the default audio track? Or is there a video format that I can transcode to where this won't be a problem?

Thanks for any info.
