Tried it. No problems under windows, bicubic scaling without any
problems. Choosen coefficients give very soft picture though, definitely
softer than default mplayer's bicubic sws, almost as blurry as "bicubic
spline" mode in sws ;)

So er.. what next?

Note than these broken lines don't appear in one place, they move as I
resize the window. Also now I think on every file there is a chance not
to meet this defect (unless trying to change b/c/s), but it's very slim
on some of them and close to 100% on others.

Btw, according to manpage lscale/cscale should work with yuv=4, but they
just give a very broken picture withc hardly resembles original image..
