It seems to depend entirely on the source material.

I use the same scripts and commands for every show I
archive, but every once in a while I see it happen.
I don't have any examples of it laying around at the
moment, I was just wondering if there were any ideas
(or even known problems) that might cause it.

What does the concat filter do if the files being
concatenated have different offsets?
