IONEER DVD-RW DVR-107D I/m sure that there are many Mac users out there who are far more'clued up' on these DVD/rws, than me, so I someone can help with this one. Computer: G4 450 dual processor OS: 10.3.7 I have replaced my original DVDR/CDR (actually a Hitachi Model GD-7000 DVD-ROM, with the a PIONEER DVD-RW DVR-107D. My system profiler recognises it as follows: Manufacturer: PIONEER Model: PIONEER DVD-RW DVR-107D Revision: 1.15 Drive Type: CD-RW/DVD-RW Disc Burning: Apple Supported/Shipped Removable Media: Yes Detachable Drive: No Protocol: ATAPI Unit Number: 0 Socket Type: Internal It recognises and reads CDs. However, when I try to run a dvd, ie Apples iLife installer DVD, or a pre-recorded DVD the drive ejects it after a couple of minutes inactivity. I have loaded Patchburn 3 which tells me "The selected CD/DVD writer is also supported by Mac-OSX. No need to patch anything! I have tried the jumper in a couple of different positions. Would it work in slave position? I am about to purchase Toast 6. I have not tried burning acd from the drive. Having just written that, I think I will reboot in OS9 and see if Toast 5.2 will burn a disc. In short; can you tell me how to get my Mac to recognise and read/write a DVD. Thanks in anticipation of your help.
