Hey, I have an Imac G5 and I've followed you're guide and when I burn a video ts file with toast titanium 6 the way I'm supposed to about halfway through the burn if says hardware failure, sense code: 0x03, 0x01. I've tried every thing I can think of like setting the buffer underrun and writing at the slowest speed and having nothing open but this happens everytime. I got popcorn and it did the same thing, even when I tried to burn it as an image. I out of ideas and desperate for advice. I called mac and they said it wasn't my superdrive because it burned a dvd with iDVD, which it always will. I also ran my hardware test disk and no errors were found. I'm in a pickle and I could use some help. Thanks.
