Might not be relevant, but I notice this code in ivtvdecoder.cpp:


ntsc = true;

if (ioctl(testfd, VIDIOC_G_STD, &std) < 0)
    perror("VIDIOC_G_STD");
else
{
    if (std & V4L2_STD_PAL)
        ntsc = false;
}


and later:

int video_height = 480;
if (!ntsc)
{
    video_height = 576;


If noone has any better suggestions, might be worth hacking this code
to force ntsc to false and see if it makes any difference.
