Transfering iso from PC to Mac 4 burning

[DVinci]

Since I don't have a DVD burner, I'll be burning my video on a Mac (using XP Home). But I need some help:

- will there be any compatibility issues bringing over the ISO and mpg2 video?

- the file is 1.78 GB. What program should I use to split it into 700 MB segments? Do Macs recognize rars?

- I will also be burning a DVD with the ISO and video on it, totalling 3.56 GB. Should I do anything before it?

If it helps, I think the burning apps I'll be using are "DVD Studio Pro" and "Toast".

Thx!

Toast and DiskCopy can handle iso's just fine. Rar's also work in Mac, I like using MacParDeluxe, but others use Gumby or UnRarX or even stuffit. Is the iso already authored? If so you will need to extract some files to bring them into DVD Studio Pro. Otherwise simply burning the iso (once whole again) as a disc image in Toast works too.
