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.
