Thanks for your reply.
Sorry about the delay in may reply but I had some Mail problems.
I have tried your solution making:
mknod video4 c 81 4
chown root.root video4
chmod 600 video4
mknod video5 c 81 5
chown root.root video5
chmod 600 video5
mknod video6 c 81 6
chown root.root video6
chmod 600 video6
mknod video7 c 81 7
chown root.root video7
chmod 600 video7
mknod video8 c 81 8
chown root.root video8
chmod 600 video8
or running the script :)
su
cd /dev
for ii in 4 5 6 7 8 9 10 11 12 13 14 15 16 ; do
mknod video$ii c 81 $ii # char-major-81-[4-16]
chown root.root video$ii # owned by root
chmod 600 video$ii # read/writable by root only
done
I have also altered the bttvp.h file in the driver to:
#define BTTV_MAX 8 // old value was 4
...
#define MAX_OPENS 8 // old value was 4
#define MAX_VBI_OPENS 8 // old value was 4
my dmesg is:

But I still can´t open the created /dev/video4, /dev/video5, /dev/video6

The function OPEN fail's.
It gives "No such device". What can be wrong?

Wrong. You get a /dev/video<n> device per bt878 chip.
You also have to build your own bttv with BTTV_MAX set to 8 to get
actually both cards running.
