I have a Kodicom card with only one input working after using the configuration from the wiki:
/etc/modprobe.d/bttv.conf
1 card:
options i2c-algo-bit bit_test=1
options bttv gbuffers=16 card=102,102,102,102,102,102,102,102 radio=0,0,0,0,0,0,0,0 tuner=4,4,4,4,4,4,4,4 chroma_agc=1 combfilter=2 full_luma_range=1 coring=1 autoload=0
The 8 inputs are from /dev/video0 channel 0 to /dev/video7 channel 0.
I've checked /dev and there is only video0 but no video1-7.
