*help please!* - converting dvd

ok, I'm new to this Mac Biz and need some major help. I have a presentation tomorrow that I'm doing with power point. The other people in my group have PCs and it is important that the files I work with on my iBook are able to be transferable. So here's my dilly of a pickle:

I need to take clips from the movie The Virgin Suicides and insert them into a powerpoint. None of them are very big clips, it's just vital to the presentation. I used Mactheripper to rip everything from the DVD but now I'm left with a bunch of IFO, VOB, and BUP files that I can't get into any program to work with. I have imovie and quicktime pro to work with.

How do I go about converting these files to something I can use in one of these programs?
And will I really be able to move the files to a PC or am i really just wasting my time?

*Please* any help that you can provide would be wonderful!
