in saa7134-tvaudio.c you have this line: static const int carr_pal[MAX_SCAN] = { 5500, 6000, 6500 }; why are there three values for pal, and just one each for ntsc and secam? What is it? I have to change that line to only read 5500, else I just get noise (like an untuned radio channel) 1 of 4 times I switch channels. No pattern at all. This is absolutely not an issue for me, I'm very much capable of changing this myself. I'm just curios about what it does. Best regards, Stian
