em28xx:cross row noise only with S-video input

The nice thing about Linux is that every step you make, behind the corner there is always a surprise.
The surprise today is this:

I have two versions of Arch Linux installed, both updated to the state of art. One with the last driver em28xx of linuxtv.org (rev 13044) for PCTV USB2 and the other with the driver em28xx-new-hg 0.20090409-1 downloaded from AUR for the card Terratec Cinergy XS.

In both systems, the operation is perfect with both analog TV and composite video input.

If, however, capture from s-video in both systems appear horizontal lines that occupy the entire screen the width of ten pixels. The visibility of these lines depends very much on the underlying color. With the blue are very visible.

Note that in both systems have also installed windows that gives me very good results even for the S-video.

Changing the format of capture in mplayer and v4l-ctl2 in every way possible does not affect whatsoever the problem.

Is there any Guru em28xx that can give me a hand?

Thanks
