i'm also gonna add.....

as i posted above, for ripping the dvd i use mac the ripper but this is not a burning/copying program.

i use roxio's "popcorn 2.0 to burn and copy to ipod format. it's simple to use and if you don't mind a slight (and i do mean very slight) loss of quality, it has a compression feature where you can fit a double layered dvd (8gb) onto a single layer dvd (4.7gb)
