As you maybe have read in my last post, I have problems receiving PAL channels. So I tried an old kernel (2.2.17-21mdk) with an old version of bttv (0.7.35). With this configuration I can see PAL channels and SECAM channels as well. With my configuration (kernel 2.4.4 + bttv 0.7.67) I can only see SECAM channels. Note that my modules.conf is the same in the two cases : alias char-major-81 bttv options tuner type=3 options bttv pll=1 card=27 I haven't found big differences in the sources for the 'struct tvcard bttv_tvcards[]' and the 'static struct tunertype tuners[]'. Please help me to solve this little problem. Thanks. PS: Sorry for my bad english.
