hm, but by reading from the DB field, you don't know which the video PID 
is. I didn't think of that back then. Should we just assume that the 
user used mythchannels to set up the channels and thus that the PIDs 
have a certain order? What, if there's an AC3 stream, but no subtitle 
stream, for one channel, while there's a subtitle stream, but no AC3 
stream, for another channel? Any suggestions how to solve that while 
still keeping the DB and code simple and flexible (for stream types we 
don't have special provisions for)?
