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.
