Which type of DVDs are you using? You don't necessarily need DL disks for a MPEG if just over 1gb. Regular DVDs support up to 4.5gb of files.
I don't know if fink gave you this website, but here is where I go for video help. I'm a member there also.
www.videohelp.com They can answer any question you have on this subject and direct you to which tools (free or bought) that work best for them. Joining the site is free.
As I told you in your other thread and so did fink, you need a program that burns DVDs because Windows XP's burner does not.
