Nope, mpeg4. And like I said, the one that sticks is either the first
frame in the recording, or the last frame in the recording.

I believe that mythtranscode already does this.

Same thing. back ANY amount moves you forward one frame. Much like
when you try to go to the end of the recording, you hit something
not-quite-the-end, and forward any amount moves you forward one frame
until you hit something that sends you back to the first frame in the
recording.

Yeah, works great.
