First and foremost I should tell you that I am a new convert from Windows. I'm currently running OS X 10.3 and find that I can not read any of my DVD+R discs but I can read my CDRs just fine. My guess is that the optical drive is simply too old to recognize the DVD+R format. Is this correct? My alternative to this would be to purchase a firewire external drive enclosure and put one of my newer dvd burners in it, but would I be able to boot from this type of connection or do I have to actually buy a "superdrive"?
