Sorry, I should have stated more clearly that this bitrate-raise is only
on the video-pid (pid 101).

But isn't the EIT on a completely different PID? Thus the EIT should
have no impact on this raise.

I'll take a look at it. But since I need to do it on the fly (since I want
live-streams) I'll probably need to roll my own.
I found a description in iso13818-1 section 2.5, but this is somewhat hard
to read =:) Are any more comprehensive descriptions avalable?
