Ah, right. That gievs me a usable picture, but no sound. Sound is in an 
extra pid in my channels.conf, like so:


NRK1:658000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_2_3:FEC_2_3:QAM_64:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_8:HIERARCHY_NONE:512+259:640:1009


The default demuxer finds that, no problem, see output below. How do I 
convince mplayer to find the AAC sound while using -demuxer lavf ?
