Most everywhere, I believe someone in the other thread about burning posted they bought a copy at London Drugs just a few weeks ago. Now I dunno if you can still burn copyrighted movies with it or not?!?!?
I have never used it. Since for making DVD 2 DVD backups I use DVDshrink and for DVD to divx (which is 99% of what I do) I use a set of tools called Gordian Knot. Best thing about it is, it preserves the dolby digital 5.1 sound tracks on your .avi file you rip off the DVD.
