bup and ifo files not supported by windows vista?! what to do!?

Hello! I have tried to burn DVDS with movies and slideshows from my roxio
creator 10 program, but they don't work, even though it goes through burning
process. I saved the file to my videos, and the ifo and bup files involved in
the program aren't opening with any program, including media player. What can
I do to burn a DVD that works in a regular DVD player?!
