I get the error "LoadPlugin: unable to load 'Repair.dll'". Thank you for clarifying on the OpenMP issue. Again, I would like to ask what version of RemoveGrain/Repair your versions are based off. I ask this because there are two versions in "common" use.
Edit: ConvertToYUY2(interlaced=true) crashes your Avisynth64 build with SetMTMode(2) and causes an exception without SetMTMode.
Edit2:
http://img43.imageshack.us/img43/50/avisynth64.png I'm liking the direction this project is going in. With masktools2 built, I can upgrade from "crude mvbob" (no error checking) to proper mvbob. Hopefully we can get some other volunteers to build plugins, so JoshyD doesn't have to do all the work.
