Hi, I am running a MacBook Pro 2.2 GHz with a MATSHITA DVD-R UJ-857E drive. Recently I have been trying to burn some video_ts files ripped with MacTheRipper on to 8x Memorex DL DVD +R. I think the problem here is that my drive is only built to handle 4x speeds. I have tried decreasing the speeds in Toast this however has no effect and I still receive a drive error. I have also tried to transform the video_ts folder into multiple different types of disc images and burn them to the DL DVD from the disk utility function. The error I get from here is also a drive error. If anyone could give me some advice as to what to try next I would be greatly appreciative.
