I've tracked the problem down to an actual bug in the bktr driver where a frequency offset was taken from the current channel set. If the program doesn't use channels, then the wrong offset may be used. I've worked around this by having xawtx/motv and mplayer choose a NTSC or PAL channel set. I also have a fix for the driver itself, but I haven't tested it yet. Try out this patch for xawtv/motv and tell me how it works for you: http://www.elsasser.org/~joshe/xawtv-bktr-workaround.diff -jre
