Hmm, a Gentoo package maintainer said: "I'm waiting for .14 which
simplifies some build procedures. Should be out in a week or so."
So I'll just patiently wait. :-P

Doh, a PVR250 will even do on an EPIA... (though those have hardware
playback acceleration). Well, I use a Terratec Cinergy 600, that's a
'normal framegrabber' card.

>From the original mail:
"- The "linearblend" filter
This is the filter that is used when "Deinterlace playback" has been
checked. It is a simple deinterlacing filter that ignores parameters,
and works by blending adjacent lines. It replaces combing in interlaced
video with a less distracting "ghost" image."

Kerneldeint looks smoother to me. Actualy my mother (yeah..) mistaken the
Myth output with the real output (though the PiP I used actually tells
which is the real one..)
Just disable the deinterlace widget, and put a plain 'kerneldeint' into the
Custom filter box. I think the deinterlace widget needs a overhaul to be
able to chose both types of filters.
And having a general overall recording-filter option would be handy too.
