I'm now up to the part where I'm exporting and converting the DV file into DivX. I also downloaded D-Volution 2 (I guess it's the most recent version of D-Volution). I followed it exactly but during the converting process, it stops and I get this message:

This always appears toward the end of the conversion... and I have no idea how to fix it. When that message appeared, I thought it meant the ffmpegX program, which is weird since it wasn't even open during the conversion. So instead I converted the movie into a QuickTime file but I still want to try to convert it into a DivX file.
Any help at all or suggestions on other video conversion apps (that can work on a Mac) with be greatly appreciated... =D
