I just had iSquint convert a 350MB TV show (DivX) to an iPod H.264 file using the 'Go Nuts' setting. It took about 12 minutes. I have a mac pro 2.66Ghz, 2GB. I don't deal with video, so I have no idea how long something like that should take. Does that seem pretty quick though? Attached are details of the original video file from Quicktime.
