My sempron 2400+ is apparently pretty close to your XP 2000+, and I get
7fps. No denoising BUT I do use the crop feature.

I transcode vcd-res captures to KVCD on my XP 2200+ Windows box at
somewhere around 60 fps using TMPGEnc, *including* running telecine on
it first! (converting to 23.5 fps video).

I tried converting & transcoding in Windows too... I installed the
dsmyth filters, and I could *see* it, but when I converted to mpeg or
avi the sound was out of sync. It seems to export perfectly from
nuvexport though. I'd do the XP way, but it doesn't seem to be an
option. YMMV.
Basically we have to figure out what Lonnie's got that we don't.
