Good idea. Sounds right. I did it:

[mythtv at mediaserver dev]$ ls -l | grep dvb
drwxr-xr-x   6 root   video       120 Mar  4 18:10 dvb
[mythtv at mediaserver dev]$ ls -l dvb
total 0
drwxr-xr-x  2 root video 200 Mar  4 18:10 adapter0
drwxr-xr-x  2 root video 200 Mar  4 18:10 adapter1
drwxr-xr-x  2 root video 200 Mar  4 18:10 adapter2
drwxr-xr-x  2 root video 200 Mar  4 18:10 adapter3
[mythtv at mediaserver dev]$ ls -l dvb/adapter0
total 0
crw-rw-rw-  1 root video 212, 1 Mar  4 18:10 audio0
crw-rw-rw-  1 root video 212, 6 Mar  4 18:10 ca0
crw-------  1 root video 212, 4 Mar  4 18:10 demux0
crw-------  1 root video 212, 5 Mar  4 18:10 dvr0
crw-------  1 root video 212, 3 Mar  4 18:10 frontend0
crw-------  1 root video 212, 7 Mar  4 18:10 net0
crw-rw-rw-  1 root video 212, 8 Mar  4 18:10 osd0
crw-rw-rw-  1 root video 212, 0 Mar  4 18:10 video0

But mythtvsetup for a dvb card gives:

Card Name:   Could not open card #0!
Card Type:      Permission denied

So I  chmod -R 777 /dev/dvb

Then I got:

Card Name:  Could not get card info for card #0!
Card Type:    No such file or directory

What is mythtv looking for?

Aha. /etc/hotplug/blacklist didn't work. The kernel inserted the module 
before udev. But I mv cx88_blackbird and cx8800  out of /lib/modules.  dmesg 
now gives:
