I have to say that I use a PVR250 and an nVidia card as well (GeForceMX440). I 
would agree that playing with the interlace settings can get rid of a lot of 
the "fast moving quality" problems. And yes, I do see them occasionally, 
especially if I turn deinterlace off entirely.
 
Generally the problem with fast moving usually ends up with a "tearing" effect, 
or a jerkiness especially in full-screen pans. Using both XvMC and kernel 
deinterlace yields (imnsho) a picture that's almost indistinguishable from my 
satellite box hooked directly to the TV... that is if you can ignore the 
occasional obvious compression artifact (like when the video changes suddenly 
seeing a frame or more of what looks like "low-res" video). My wife and kids 
don't notice it, though... I only notice it because I'm a perfectionist.
 
The only problem with this setup is, of course the flickering OSD. Still, we 
just live with that for now.
 
I have noticed that the video looks a little better in terms of fast movement 
when transcoded to MPEG4... but I don't like the amount of color bleed that 
MPEG4 allows which MPEG2 doesn't. Might be fixed with a few fiddles with the 
transcode settings, but I've not dedicated a whole hell of a lot of time to 
that yet.

        Could this be due to your output method, rather than the capture?
        I've noticed it too since I stopped using my PVR350 for output and
        started using an nVidia card.  Changing the de-interlace algorithm
        improved things to the point where I hardly notice it now, but it's
        still there.
