Perhaps. Though other reports say that with XvMC support enabled,
de-interlacing won't work, so you'll likely have other problems. :(
I presume you already have jitter reduction enabled, along with
de-interlacing... You might try bumping up the resolution and/or
bitrate on your captures and see if that helps. I see very few problems
with my PVR-250's 720x480 8/16 captures. (Then too, I may just be used
to it, after six months of not watching TV any other way ;-).
