I gave up on capturing video with VF (it would never recognize my DV camera, while all the other software I have, did) and have been capturing with Movie Maker 2 and Movie Factory.
MM2 is great for capture from a recorded DV tape, but isn't usable with my (Sharp) camcorder in its VCR (pass-through) mode, i.e., when using it as a converter to send analogue stuff to the firewire card.
MF is very good at what it does, but what it does is record video and audio as separate video (*.avi) and audio (*.wav) files. Does anyone know how to use MF so it doesn't do this, or re-unite the files in VF (other than by crudely trying to line up the audio and video on the timeline)?
