What do you mean wit "mux"?
I use a plain vdr without any plugins or patches. 

At the today's recording of "Dr. Stefan Frank", vdr did an emergency exit 
with "ERROR: video data stream broken" and everything was fine.

I ask me, how serious the "ERROR: unknown picture type" is and why the 
default behavior is only an error message, altough if there are many of these 
errors at a recording, the recording is completely corrupted and a restart 
would solve that.

I applied the the patch, but maybe it is possible, to add a counter, which 
measures the number of this errors and made only an emergency exit, if  there 
are too many of them at a recording (because as you see, with heavily zapping 
one of this errors occours and there was nothing serious else).
