Damn - this is starting to worry me...This is the same exception that was thrown before but I don't know why.16/04/2009 17:45:04.429 RunGraph() threw exception: A device attached to the system is not functioning.
The graph built perfectly (as far as I can tell from the logs) including adding and connecting the MonoGram AAC decoder.
It's almost as if running dvb radio once is fine (e.g., when you scanned for the stations) but it then 'hangs' the tuner. I haven't come across this with anybody else and there's no indication in the log that things haven't been cleaned up correctly.
Let me know what happens with the new drivers.
EDIT: PS, I reckon there's a good chance that a reboot would result in you being able to play the radio successfully...urrrm, maybe
