Peter, thanks for your reply to the list - very helpful.

Thanks - I patched the files concerned (manually - for some reason the
patches wouldn't take), and they compiled, when I found a version in
CVS I can use! Apparently dvb-kernel CVS swapped over to insisting on
2.6.13rc+ yesterday? Anyway, I've patched CVS code from the 6th June
(using 18.104.22.168 here).

No I don't see any such messages, unless I need to turn verbosity up somewhere?
Again last night, same experience - I managed to tune into one channel
with tzap -> mplayer, which locked up after maybe 10 seconds, and now
I can't tune into any. I had no problems whatsoever in dvb-kernel/apps
from 2004-12-26 and an earlier 2.6 kernel, so I'm really stuck here.
Is there anything else I can do or am I stranded with dvb-kernel now
and this box?
