I've spent a whole day trying to get Avisynth file open somehow in Vegas 4.0e. So far I've tried:
- Frameserving using VFAPI and Virtual Dub
unfortunately VFAPI just says: ???my.vdr??? in a window and wont create an AVI.
- Wax. Crashes and is slow as molasses. Standalone Wax 2. opens the files OK but has problems in rendering
