when it is included in the dvb recorder to record to multiple files, we 
also need to implement to allow the use different pids for the files so 
we can use another channel from the same mplex!

how far are you with your implementation, and are you still working on 
this or not??

and have you seen that in the myth-eit branch a lot of the dvb things 
changed, so we need to implement the patches to this... ???

and i see your scheudler patch works like mine, i also thought of adding 
a field to the programm info, by mine was only a first quick dirty hack! 
i also think that there are a little more changes to do, because now if 
due some recordings for example a channel is recored on the second card 
and then ther comes a programm with the same mplex, but the first card 
is free i think this one is used (need to be checked). but if it is so, 
the first card is blocked but it is not needed! but that is a later 
problem, if everything works...
