I backed it up using Magicdvdripper541 and they saved as .vob files. So I used Autogk to convert them into .avi. files but the problem is that when I try importing them into windows movie maker it tells me "the codec required to play the file is not installed on your computer." And when I try to import it to 'Everio Mediabrowser' the software that came with my videocamera, it tells me it can't be imported... What am I doing wrong or what should I do?
