That's not surprising, given that fxtv will simply just throw away one field 
if the window is small enough (and perform no deinterlacing at all if you 
pull it up to full size, i.e., full interlaced glory).

I myself use -vf lavcdeint,denoise3d=12:9:18 for watching TV and I'm quite 
happy with it.

Composite video vs. split Y/UV actually should be expected to look different 
(i.e., S-Video should look better).

On my oldish Pinnacle PCTV, I need to connect the external lineout to a 
line-in on my soundcard to get audio. Recording that audio with mencoder is 
just a matter of setting the recording source to the line-in and turning up 
the rec mixer ...
