I just replaced my CD drive on my PowerMac G-4 with an internal Pioneer DVR-109 DVD/CD Writer. I installed Patchburn 3.1 and am able to record and read most DVD disks, but I can not read DVD-Video disks. The computer tells me that it does not support the format I want. I am trying to read Video_TS.BUP, IFO, and VOB. I am using Panther 10.3.9, and my Mac is 467 MHz and my AGP Card is ATY Radeon 9000. What firmware do I need and how do I obtain it. Help please. Thanks
