Problem - Video4Linux & bttv Video capture - PAL/SECAM mess

Hi, I have bttv-based Video capture card (with 4 PAL surveillance cameras connected). The card works, video signal coming from all ports, but there is a nasty and annoying problem - PAL/SECAM mess. Time to time I have to launch XAWTV or TVtime and switch setting back to PAL-NC. Even worse, sometimes it works, sometimes not. Someone can tell me how I can globally save setting for ALL video devices to PAL-NC for ALL video grabbing applications? I have even run XAWTV and TVTime as root - did not helped either (with 2.4 and 2.6 kernels). Thanks in advance for any suggestion(s) Andrei (aka MacGuru) http://snow.prohosting.com/guru4mac/
