[linux-dvb] Re: black picture after channel switching

[ma.hoff@t-online.de (Martin Hoffmann)]

For me just the same - but if i do not switch channels and do not run epg 
scan then it seems to work forever !
Then i Switch only one channel and it's black !
Reloading the drivers cures this !

This never happened with my 1.3 revision card - just with my new 2.1 !

Does anyone know some kind of debugging (vdr / drivers) or verbose output 
that could help to clarify the problem ? /var/log/messages says nothing about 
a problem ... Would be nice, if it could get fixed...

Martin.
