hmm. my 1st test (only with demux stuff changed) resulted in an null pointer exception...i think this is because of mixing stuff up...Great! Because of the pre-2.6.0 code freeze the changes between 2.6.0 and 2.6.1 were rather large. I would rather suspect the bug in av7110.c, but maybe we can rule that out if you have success with your dvb_demux experiment.
