Good qestion - i just borrowed most of it's code ;-)

Yes, that's a big problem. Although snapshots in xv-mode are not that great 
under kvdr - or did'nt you experience a problem here?

But one could do that in xawtv easily too - instead of feeding the data in 
the xv take the same date and store it as a snapshot.

currently i did the less elegant solution: i switch to RGB-mode, take one 
frame and switch back, although jpeg are compressed as YUV anyway...

That's true, but one could do it as following (which might be a nice idea for 
kvdr too):

capture all the frames and write them to a single, location by 
1. skipping every second pixel/line -> gives 4 overlays side by side
2.overwrite part of frame 1 with data from frame 2
and feed it to xv.
