Hey guys just a quick question. I have the 12" PowerBook with combo drive because the superdrive is a rip off. I'm going to get a USB 2.0 or Firewire external dvd burner. Just curious though when I run idvd now it says I don't have a superdrive so I can't burn. Will it keep saying this and not burn even with a 3rd party external? Just don't want to buy an external one and find it doesn't work on the mac with idvd and such, I'll just get a cheapy internal one for my pc instead. Thanks!
