Converting slideshows from Mac to PC

Hello,

I've recently created a great slideshow in iMovie on my old mac powerbook, but it is unable to burn DVDs. The only DVD burner I have available to me is on a PC. I've gotten the slideshow to play at high quality on a PC by just burning the 3 files (.mov, media folder, and iMovie project file), and copying them to the PC.

That works great for viewing the slideshow, but from what I understand, it's difficult/impossible to burn a dvd of the slideshow when it's in that format (the 3 component files). I'm curious as to whether I can compress them all into one .mov file (or, ideally, an .mpeg file or one that burns to DVD on a PC) without losing image quality. My mac can compress the file for export, but it loses a lot of image quality, so I'll need to find another way around it.

My PC-using friend is pretty tech savvy, and he thought it might be possible to use an application called Frags (sp?), which will allow him to record the audio and video of what is being seen on his monitor (i.e., the slideshow), which he can then save into a PC-friendly format that he can burn to DVD, but I didn't know if any of you had any other suggestions.

If any of you have had any experience transferring iMovie slideshows from mac to PC--or just have suggestions for how I might pull off this little maneuver--I'd really appreciate it,

Michael
