Mmm, had a look at that and could compile it, but did'nt found a way to 
choose the plugin in xawtv...

anyway - looked at the sources of the "deinterlacing"-functions and on 
"Greedy2F" from the dscaler package and i think all those routines are not 
really deinterlacing - they are just interpolating in various ways, 
effectively throwing away half the data :-(

That way it would effectively be the same setting the video-dev to half 
vertical resolution and let the xv-hardware scaler do it alone...

I think of an "shifting" algorithm, that just _moves_ the lines in place.
Something like motion detection and compensation.
Did someone found such one already?
