Hey, Yes I am trying to copy a DVD, but not illegally! I burnt a DVD using iMovie/iDVD a year ago and now I'm wanting to make copies of it, since I don't have the files on my HD anymore. Anyways, I used DVDBackup and then I use DVD2oneX to compress the files. Then I launch Toast 6 Titanium to finish the job. I'm burning a data disc (DVD-ROM UDF) and two times in a row when its just a few mins into the process this message comes up: The drive reported an error: Sense Key = ILLEGAL REQUEST Sense Cose = 0x21, 0x02 BUFFER UNDERRUN Now this has happened twice, and that two DVD-R's down the drain. Their not cheap, and I don't want to waste anymore. I'm using a G4 eMac 1ghz, any ideas?
