xbox 360 unsupported format / wont play

[white westie]

Hi

Wonder if anyone can help

Currently trying to play an mkv with ac3 but I'm getting unsupported format when I Try and play via my xbox 360... transcoding is on (limit to 2gb) and I'm using latest ffmpeg. I dont really want to "pre-transcode", Just transcode on the fly. I have the network wired into 1gb switches, I run on a i7-2600 sandybridge with 16gb ram and a decent 4gb video card, so it can handle anything I throw at it.

Running latest ffmpeg, transcoding is on and set at normal priority on the latest mezzmo, profiles are set to xbox 360

any help appreciated.
