You probably have enabled the "chroma denoising" filters in the
ADVC300. That, as I discovered, is a huge mistake. Canopus may make
a superb DV codec but the chroma filters in the -300 are wretched and
smear/ghost the chroma to the point of the video being unwatchable.
Any suggestions?
Turn off the chroma filters. The luma filters appeared to be OK but
even then I would use 'minimal' settings or even turn them off and
use yuvdenoise instead.

OK. I'll try that.
Do you see any diffence if you use an svhs tape deck - and
use svideo to the canopus - on regular vhs tapes?
