No, this fix is very specific to MPEG2 streams.

As always, I'll be happy to take a look at it if you can provide me with
the original video, and the other info I need (cutlist, and transcoder
settings).  I haven't seen any such corruption, but I don't normally
transcode from mpeg4->mpeg4, and very rarely use cutlists, so I normally
need examples to debug issues with configurations different from my own.
