I finally found a clip that VV3 consistently misinterprets as progressive scan. A small sample is at ftp://videx.serveftp.com/sclive_ohci_0001.avi (about 4mb). The clip renders jerky in VV3 but okay in Premiere6. Timeline playback is okay but I need to render due to disk space limitations.
Is this an sclive error we can tell the author about or is there a way to force VV3 to always use lower field first? Capturing with VV3 isn't an option as it discards DV audio channels 3&4.
TIA
