I think that this is where I'm not getting something. I thought that, for
the normal (not deinterlaced) case, the entire xv_image was always used.
Is there a feature that actually zooms into a *part* of the picture,
rather than juzt zooming the entire picture into some other size? If so, I
did not notice it and don't understand it yet.

Thanks. I'll try making it all work, this evening or tomorrow. One other
problem is finding a way to destroy an xv_image, but I'll look at xawtv
sources for that. (Or failing this, at libxv sources, to find out how it's
allocated).

Now a real hit for this method of deinterlacing would be finding a way of
not even *rendering* the dropped field. This would impact CPU usage and
make ogle usable for DVD playback on low-end machines. But this is a
future challenge.

P.S. what about the problem of CVS only running as root? I hope to be
using CVS after this patch so I'm interested :)
