I've been following dvgrab with a lot of interest, and just got it working last night. I'm thinking that, rather than putting too much time into figuring out how view an AVI, it would be more productive to: * Capture the video to disk using dvgrab --raw * Write a program that can read the raw file and write it back to the firewire interface isochronously, so it can be viewed using a camcorder. Since this would allow you to visually verify that the capture worked, without actually decoding it, I'm hoping it will be a (relatively) easy first step towards creating an actual DV decoder. Plus it would be an important component of a future open-source non-linear editor.
