I just want to point out that long time ago the ivtv driver code
got merged into the kernel, but with slightly different API,
that broke MPlayer compilation. I added the breakage into
the ivtv configure test.

What I'm saying is that ivtv check never succeeded for
almost a decade and this code has effectively
been disabled during all this time.
