Hey guys...new to the forum & a recent convert over from the dark side I bought a s/h powermac G4 450 recently ( running Panther) & I just love it.. There is one downside however: before I got rid of my pc I backed up heaps of music projects, photos, .avi files etc. etc. onto dvd-r thinking that the dvd-ram drive in the G4 would read them ok ( since it reads cd's, commercial dvds & even cd-rs burned on the pc just fine). But it doesn't seem to want to play ball...the discs just spin for a bit & then get spat out. I should add that I finalised the discs & checked em on the pc and they worked fine. So..before I rush out & buy a new dvd-r drive to replace it, I was just wondering if there could be any solutions to this without spending $$? thanks so much!
