I purchased this product and in the past few months have gotten it to work on 1 DVD. It bombs repeatedly. There are no docs to answer interface questions. And the developer does not respond. The last reponse a month ago was to try the latest version. I did, and after 9-1/2 hours of "encoding" I got a 25mb file that wouldn't even open in Quicktime. I'm using a G5/Dual 2GHz with 4gb RAM, so it should have plenty of power. I tried it on my laptop with the same results. Continual bombs and failure to encode virtually any DVD to the iPod.
