Whether you use XP or EP recording shouldn't matter, it'll just reduce the video quality. If you plan to import as DVD format you'll need something like Mactheripper (a free program) to transfer it as a Video TS folder (mostly .vob files) to your Powerbook's hard drive. To edit you'll need to convert the Video TS folder into another format (something like .mov, mpeg. avi, etc). MPEGStreamclip will do this well (again it's free!). You can do very basic editing in Quicktime Pro, but for more complex editing use iMovie, though it can take an age to render movies, even if you've got a powerful machine with lots of RAM.
