I posted an example on page 2 of the thread I started about using HuffyUV.

I don't want to hijack the thread but may I ask if this is similar to what you have experienced?q]
Nope. For me it would just create a handfull of weird pixels in a single frame everything 20 seconds or so. And it would only do this when exporting from Premiere.
Your problem seems to be with the way Vegas is handling the Huffyuv codec. Have you tried capturing with a different codec? Corepng is also lossless, although slower.
