TMS starts fine, runs fine, admin panel works normally and I can browse folders and video files from the xbox 360. However, whenever I select one of the videos to play it, it complains that the format is unsupported. In truth, all 230 videos are in supported formats. If I copy them to a USB drive or DVD they'll play on the xbox just fine. Same result with or without transcoding enabled.
One example of this: 640x368 XVID MPEG-4 video with MPEG Audio. As with all files, this one plays fine on xbox unless it's being served up by TMS.
What about TMS would cause xbox360 to report some incompatible filetype for a compatible file?
