OK I unloaded the cx8800 and cx88_blackbird drivers. I noticed that
/dev/video0 is no longer there. Here is what is in /dev/dvb/adapter0
root at mythtv:/etc/modprobe.d# ls -l /dev/dvb/adapter0/

How can I now test the device? I thought the DVB stuff is for RF HD only.
I tried...
dtvsignal /dev/dvb/adapter0/demux0 and still get
Signal: 000 .
Also, in mythtv-setup, do I just create a DVB tuner only? Or do I
select the HD3000 card?
Thanks for helping me troubleshoot.
