Thanks for doing this.

Testing interlaced on 600g, I notice that (like most -vo) chroma is 
getting treated as progressive when displayed as weaved, so the "teeth" 
may look twice as bad on saturated colours.

Maybe this is already on your radar, just though I would mention it.

A good way to see the effect is this test stream (39meg) -

mplayer -noaspect -vo x11 -vf scale=-1:-1:1

will display properly (well if you call weaved proper). I guess if your 
work can be extended to de-interlace then getting interlaced chroma 
correct is going to be for the best.
