Yes, this would be VERY comfortable. But as I still have not seen any
frame accurate MPEG cut tool, that also takes a look at the audio
stream, it would already be a big step forward if you were at least able
to jump back to the last I-frame - in the worst case, you have to press
frame-forward 12 times again :-).
Additionally, as private TV stations often use hard cuts between movies
and trailers, you could define that the frame you currently see is not
included in the cut file (cut point = current point-1 :-) ).
