Just read the post on the ame subject however did not address this issue that I have discovered recently. Now testing the software listed in that thread however has anyone ever come across this one before?
Got an h.264 mkv file I wish to convert to mp4 to play on apple tv. Simple enough?
Used xilisoft mp4 converter and using profiles:
Apple TV H.264 HD Video
Apple TV MPEG4 Video
Apple TV H.264 Video
All start to encode merrily however when getting to 11 minutes on the dot of the playback time of the video file it stops and says complete. The reulting file is 256,292k each and every time.
Tried another piece of randomly chosen software, in this case, Jesterware Apple TV Converter and exactly the same happens, resulting clip is 11 minds long on the dot.
Any clues?
Many thanks,
Spanner

First of all, those two application are probably crap(not getting much love around here;I personally never heard of the second one).
Download MediaInfo and post the info about your file, what video/audio codec you have.
What are the video/audio codecs requirements for apple TV(I think H.264 with AAC/AC3 audio?;most likely you already have that in the MKV)? You might be able to just use Yamb and repack everything in an mp4 container, without any conversion and loss of video quality(or maybe get away with converting audio only;that's why use MediaInfo and display the info).
If you need to do any conversion, use HandBrake and the Apple TV profile.

Give Yamb a try. The only thing that jumps out is the CABAC in your video, and the CAVLC supported by Apple TV.

Have just downloaded it and tried it. The resulting file will not import in to iTunes in order to stream unless I am missing some setting contraints here? Does not seem to have too many options available!

I don't think it'll work, you might need to re-encode, your video is encoded high profile with CABAC. Try HandBrake and the Apple TV profile.Just encode the video and the audio pass-through.
