I have a powerbook 15" 1.67ghz model (the one before the hd lcd's; got it around august 05) and it will not burn Dual Layer dvds. I know that the model is not supposed too but after doing a little research i found that the drive model: MATSHITA DVD-R UJ-845E, was a quite release into my version of powerbook. I am pretty sure that this superdrive has the capabilities to burn Dual Layer Dvd's but from more research i have found that this has been locked out by apple because they didn't want to upset those who got a powerbook without this drive(because it was a quite release). this is what is says in system profiler: MATSHITA DVD-R UJ-845E: Firmware Revision: DMP2 Interconnect: ATAPI Burn Support: Yes (Apple Shipped/Supported) Cache: 2048 KB Reads DVD: Yes CD-Write: -R, -RW DVD-Write: -R, -RW, +R, +RW Burn Underrun Protection CD: Yes Burn Underrun Protection DVD: Yes Write Strategies: CD-TAO, CD-SAO, DVD-DAO Media: No I was wondering if anyone knew away around of what i think to be a firmware issue or does my drive just not burn DL DVD's. Any help would be appreciated.
