What is the v4l module in X server?
I have these modules in xorg.conf:
"
Section "Module"
        Load  "dbe"
        Load  "extmod"
        Load  "fbdevhw"
        Load  "glx"
        Load  "record"
        Load  "freetype"
        Load  "type1"
        Load  "dri"
EndSection
"

Thanks! 
Now it makes sense also why to grab in 25 FPS and still do deinterlacing.

I hope this better explanation makes it to MPlayer documentation to
tv-input.html. Now the old one is still there:
