Hi, I just don't understand how to get my DVB board NOT to include the CI
interface. There is a CI conector on the board but nothing is connected. I
just want a stream from all channels. If I watch an open channel
everythings works ok, but if I change to a coded channel the stream just
stops, nothing comes out.

>From dmesg:
Linux video capture interface: v1.00

This is all devices I get:
[root at srv linux]# ll /dev/dvb/adapter0
total 0
crwxrwxrwx  1 root video 212, 6 Mar 12 16:11 ca0
crwxrwxrwx  1 root video 212, 4 Mar 12 16:11 demux0
crwxrwxrwx  1 root video 212, 5 Mar 12 16:11 dvr0
crwxrwxrwx  1 root video 212, 3 Mar 12 16:11 frontend0
crwxrwxrwx  1 root video 212, 7 Mar 12 16:11 net0

I suspect that ca0 is the CI interface.

Doing a lsmod gives:
budget_av              13344  0
saa7146_vv             47328  1 budget_av

tda1004x               14692  1 budget_av

(I've have two DVB-T and one DVB-S, all from terratec)

Anyone nowing about a patch which disable the CI interface eventhough it's
a saa7146 decoder?

All help is very much appriciated :)

cheers, tord
