OK, you're using "frame" as an mplayer term, not as an MPEG-2 term which
is all I know. I'm talking about the user data that arrives, for
example, after the sequence header code and before the group start code.
This isn't associated with an individual frame yet I have found caption
data in user data at this point in the stream.

But if this is the proper solution, why is it dropping characters?
