I just got the Powermac G4 in my sig. last week and I'm in the process of upgrading it. It currently has a Sony cd-rw optical drive(original?) and I would like to swap it out with a DVD drive. I currently have 2 extra Creative DVD drives(12X/6X) available to use but I don't know if they are compatable. I would like to know if one of them will work and if the system would be able to play DVD movies with the original ATI video card. Has anyone used a Creative drive and had problems? Any other manufactures recommended? I would like to use one of the ones I have on hand but willing to pick up something else. Note: I already have an external dvd-rw/cd-rw drive so I'm just looking to put in a standard dvd drive. Thanks.
