Mixer settings for the line device or record device selection
will be the problem here I think. Use mixer to set it up - my vcr script
includes:
/usr/sbin/mixer line 100
/usr/sbin/mixer igain 100
/usr/sbin/mixer =rec line

I haven't tried with NTSC but certainly with PAL capture at above
384x288 (half resolution) requires some patches to the kernel for proper
sync generation. Shprtage of CPU will also have this effect, try capture
at 320x240 and see how that goes. I can capture real time PAL at 720x576
but I use an XP2000 and use -me zero -intra to do it reliably.
