Power Mac G5 won't read DVDs
A SuperDrive equipped PowerMac G5 running OS-X Tiger will read and burn CDs, but won't read DVDs. Upon checking the hard drive "partitioning" scheme, it shows that it's formatted with the older Apple Partition Map - not "GUID". Could this be the cause of its inability to see DVDs? If I also re-partition the Hard Drive as GUID and upgrade the OS to 10.5 Leopard, will this solve the problem? (I already reset the PRAM and reset the "Open Firmware").
