I can compensate for it by reducing my TV-Out saturation to minimum but that causes the picture to be somewhat washed out. I see that the bttv-0.9 development drivers mention a fix for saturation and was wondering if anyone has had the same experience and managed to solve it one way or another. If not I may try to patch the development bttv drivers into my kernel and see what I get.

Are you sure it's really oversaturated? I've found (and at least one
other person on this list who I got the tip from) that bttv output has
way too much contrast. I compensate for it by lowering the contrast in
MythTV (hit j while watching live TV). I find about 33 works good for
most channels.
