I've been able to reproduce a strange effect with my grab.c program here in the UK (PAL video). If I run grab.c with an image size greater than half the total video size, grab.c grabs an interlaced image. If I run grab.c obnce every 2 seconds, then 1 in 5 images grabbed will have the odd and even scan lines the wrong way around. I've not had time to follow it up yet.
