depends...If you want 2x DVD-authoring, use Apple. If you are cheap (like me), try different kind of generic DVD-R 'til you find one that works...I've tried 3 different types (6 actually, but those 3 I've done 20+ burns with) and only the last type survived cross-platform test on a consistant basis. (one of them I tried had a 30-50% chance of not mounting on the PC, one of them I tried had problems with more than 16 divx files in the same directory while on the PC, and the last one was good) The one I liked was creamy white on the top, and cost only 'bout $1.29/disc <a href="http://http://www.supermediastore.com/25pac47bulun.html" target="_blank">from here</a> (I guess it's $.98 now...)
