I'm NTSC with a pvr150 (nonMCE) and a pvr250 running ivtv-0.4.1.
They have both have very similar saturation. If I had to say if one was
more saturated than the other, I'd even go so far to say that the 150 is
slightly *over* saturated, while the 250 is not.
There is a major difference in the hue though, something I've
compensated for in the cx25840 driver by adding 16 (0x10) to the hue to
push the subcarrier phase +5.6 degrees and produces similar output to
the pvr250.
