I hope someone can let me know something because as far as I've seen there still is not a mac app like XenonMKV or Gotsent for Windows that converts mkv to mp4 (without a long re-encode) and is compatible with the Xbox 360. Quicktime's passthrough method is fast but it doesn't always result in a file that the 360 can playback. Never had success with visual hub. Is there still not a mac app that is a "one stop shop" for this? I've seriously been looking for over a year and it seems something like this would be large in demand by Mac and Xbox 360 owners.
