Weeellllll....I've just checked it out again, and it's not apparent in the GOUT. I say apparent, as I keep almost thinking I'm seeing it, but can't quite decide if it's there or not. I dropped the demuxed raw GOUT mpeg into Virtualdub, and checked out the shots I posted; no streaks evident. Next, I dropped in the AVS script (v3.)17), and there they are again, same places. Weird. I'll post pics later.

INv8r,

I'm guessing that if you're not seeing it in the raw GOUT, and you ARE seeing it in the Avisynth script previous to encoding, it must be an issue with Avisynth. I haven't been keeping up to date on the latest Avisynth version and plugin versions, so maybe one of those is the culprit. I know there is a new version of MVTools out, so you may try going back to an older rev, or even an older Avisynth.
