I'm so confused about why this is happening. I have had great success in burning DVDs... until last week. I don't know what's going on. The files look fine, they are the right size and the picture is good. HOWEVER, every time i go to burn it using Toast 5/6, I get an error half way into the burn process that reads: The drive reported an error: Sense Key= HARDWARE ERROR Sense Code=0x03 It then deems the DVD unusable. I have gone on all the forums and have done a search and I don't know what is going on. I've tried reinstalling the software, but nothing has worked. I'm using mactheripper, then dvd2onex, then toast. I have also tried using Disc Copy to burn the image file (which i've made using DVDImager. I still get an error. Thank you to anyone who can help me. I'm in a jam and it's driving me crazy. Thanks.
