Thanks in advance for any help given. I have a Rev. A iMac G4 running Panther. A family member gave me a new external dual layer DVD burner for my birthday. My dilemma is that it uses USB 2.0 to connect to the computer. My iMac only has firewire and USB 1.0 (which is much too slow to burn DL DVDs). Does anybody know if there are any USB 2.0 adapters that would work with my firewire ports? Or is there another way to hook up this external burner? Any help would be appreciated. Thanks.
