Sorry if this has been posted before...I'm new to the Mac world. Just bought a DVR-111 superdrive for my g4 to replace the old CD-ROM that came with the computer. First time i tried it the system wouldn't show up, so i moved the jumper from master to cs position. Shows up now in system profiler but won't run any DVD's, so I figure i need burning software. Should I go with the Roxio Toast or the Dragon? Should i move the jumper back to master first? BTW, running on dual 533MHz, 768 MB SDRAM. OSX, 10.4.10. Any help you could give me would be very much appreciated. If you need more info let me know.
