I believe that is true, but not exclusively. As mentioned in another
post, I passed my DVD thru VideoReDo, which supposedly corrects MPG
sync errors, and imported the fixed file into MF4. It managed to
corrupt it somehow.

As mentioned earlier, I have this suspicion that this one scene that
is particularly bad in terms of frame freeze and aucio sync problems
is caused by the fact that it is obtained from a compressed DVD I
made. I am trying to get my original back that I lent out so I can
work with an uncompressed DVD.

I tried MF4 out on original DVDs and it worked perfectly. So I think
the problems are caused by over-compressed content which even an MPG
correcter like VideoReDo can't fix.

The compression that DVD Shrink uses must be very aggressive. And
somehow MF4 is unable to deal with it, even when the file has been
"fixed" with VideoReDo.

If this is what is going on, then the solution is obvious - don't use
compessed video in MF4 - get the original and work with it.
