The problem I had with MPEG editors was not
many of them would do a frame by frame edit.
I thought this was because the programmer didn't
want to put in the effort to do it right. I thought
you had to back up to the previous complete frame,
then apply the differences in the following frames
to generate a new complete frame where the splice
was to happen. Are you going to handle editing to
arbitrary frames? I believe you have to do something
analogous in theora/ogg.
