Trying to create highlight DVD

[Jesus Shuttlesworth]

I am trying to help my brother create a highlight basketball DVD on his laptop by using clips from different game DVDs he ripped onto the computer. I am having trouble getting the program to work because DVDs that where ripped are only coming up as NTI CD & DVD Maker files and aren't compatible with any other program. The videos also aren't even playing on the computer. I am trying to get the files to work with CyberLink PowerProducer but nothing seems to be working. I tried changing the files to open up with CyberLink rather than NTI CD & DVD but that didn't work so I don't know...

It's on a Windows Vista..if that helps any
