I've run avprobe on the videos that are not displaying and notice the
following warnings:
[mov,mp4,m4a,3gp,3g2,mj2 @ 0x1315320] multiple edit list entries, a/v
desync might occur, patch welcome
If I use a later version of HandBrake (0.10.3) to convert the videos, I
don't get the warnings with avprobe and the videos display ok on my BQ
4.5 (the originals were created using HandBrake 0.10.0 according to
avprobe). The output from avprobe for the non-displaying and the
displaying videos are shown below.
Video no longer displaying:
