Hi!

Please take a look at this screenshots:

As you can see, I get a picture with some annoying interference
patterns, with temporaly constant wavelengths (one for the x, another
for the y-axis) but changing phase (they "move" when you watch TV or a
recorded video). I only get this when watching this chanel, but I don't
know why. (All other chanels look ok - I think it's a resonance-problem
I can't correct.)

Ok, now this chanel ist broadcasting my favorite TV-serie, and I want to
record it using mencoder :D. But this interference patterns are
annoying, and I want to eliminate them. As this patterns are oviously
produced by only one wavelength (well... one per axis), I thought in
eliminating this wavelength by a filter (as MPEG? makes use of FFT, this
shouldn't be a problem). But: is there a filter to do that? Can anyone
tell me how to configure that? I can't find anything in the
mencoder/mplayer manpages.

Thanks in advance!
And I apologise for my poor english :)
