To briefly get back to the original question, I use DVD2one for burning, its quick, really simple to use and best of all it squishes great big files onto teeny weeny dvds lol
I got the whole of Doctor Who 2005 (including the Christmas Invasion, making 14 episodes) onto 3 dvds, and the quality is excellent.
And before anyone jumps on me about copyright etc, these are back ups for my own personal use.
