Comment:

 pos 501277 is not the keyframe for this track of TrueHD, so this is just a
 bug, I imagine.

 For those that do not get it, this timestamp should be 0.092, not 0,
 coming from that adler-32 block with checksum 0xf3858bc9 and timestamp
 0.092, not to mention that position in file is not 501277, but 558728, it
 is literally first key frame mkv and tagged as such.
