Thanks for the earlier help Kenneth,
 
I haven't managed to get dvbstream to work yet, the latest version is
looking for sec.h and that isn't in the kernel or LinuxTV drivers?
 
Mainly, the DVB-T audio video/sync problem seems to be that:
 
1. Channel 5 (a QAM64 channel FEC 1/2) channel seems to resync. I get a
silence period every so often (4-5 minutes) and the audio resyncs. Seems
watchable apart from the odd 1/2 a second silence where the audio
resyncs.
 
2. BBC (QAM16 FEC 3_4) channels always go out of sync (audio always runs
behind the picture). On the console I see (not sure if it all correct as
I'm not sure I got it all when I copied it):
