Problem whith TV card no /dev/video0

[Claude Petrini]

II try to make function a TV card with chipset bt878 but the device 
/dev/video0 is missing.

dmesg  |  grep  bttv  give  :

bttv: driver version 0.9.15 loaded
bttv: using 8 buffers with 2080k (520 pages) each for capture
bttv: Bt8xx card found (0).
bttv0: Bt878 (rev 17) at 0000:00:0d.0, irq: 5, latency: 32, mmio: 0xcfcfe000
bttv0: detected: Twinhan VisionPlus DVB-T [card=113], PCI subsystem ID 
is 1822:0 001
bttv0: using: Twinhan DST + clones [card=113,insmod option]
bttv0: gpio: en=00000000, out=00000000 in=00ffffff [init]
bttv0: using tuner=4
bttv0: add subdevice "dvb0"

In the /dev directory there is no device video0.

Any idea?
