You haven't been reading this list carefully.
Go to gossamer threads, and search on my name for more help. This has 
been discussed at least 5 times since the beginning of the year, under 
various subject titles.

The quick answer is that you are using the WRONG module...Your HD3000 is 
  outputting through /dev/video0 NOT /dev/dvb/adapter0

Try modprobe -r cx8800 followed by modprobe cx88-dvb
and look at the tail of dmesg to see if your card has properly loaded 
and loaded its firmware.
