Why not just get an external burner for your mac?

Here are a few:

SAMSUNG USB2.0 Slim External 8X DVD Drive 8X DVD+R 8X DVD+RW 6X 8X DVD-ROM 24X CD-ROM $64.99

There are more at http://www.newegg.com just do a search for external dvd burner.

Unless you want the VHS part too. I don't know if you can with those.
