** This bug is a follow up from bug 740575 **

So for now we went forward simply shifting the segment in present of an initial
CTTS to bring back that first PTS to running time 0. While this is the only way
to achieve AV/Sync in older version of the spec, there might be other technique
in the field. This is relate to a change in the CTTS format, where the value as
been made signed presumably to work around this synchronization nightmare.

I think the real task is to find older and recent sample mov movie, encoder
with other muxers and analyze their muxing behaviour. Base on that we should be
able to take a decision upon the synchronization strategy to adhere with to
correctly render the MOV and MP4 files with image reordering.
