This issue occurs w/ audio AND subtitle tracks.
Attached 8 screencopies (tvOS, iOS / 4 each / 4 working, 4 not working).
According to my testing, I can rule out 3D and .iso-size.
However, total number of audio and subtitle tracks could be the root cause.
I believe James meant that he also wanted you to post the results using the MediaInfo application which is a free download available at: http://sourceforge.net/projects/mediainfo/
Any progress on this defect? As said above, audio and subtitle tracks are not being identified. Thanks a lot for looking into it. You guys deliver a great product.
