Well first, you can see my specs at the bottom of my post. Second, i've got a business that i'm heavily using my iMac for. DVD authoring, video manipulation and the such. Usually when i'm burning a DVD i like to use the background encoding feature. My question is whether i can have my Mac do that in the background and possibly even burn a DVD while i'm on another users name? I want to be able to keep work completely seperate from my personal stuff. I feel that a seperate user name would accomplish this, but i want to be able to switch back without having iDVD quit out on me. Soooo, will it keep background encoding while i'm on another name, and if so, will it also burn a DVD while on that other name? Thanks!!!
