"illegal Sense Error" Trying To Burn Dvd+R-Dl

[jweisbin]

I am trying to back up iTunes movie files (.m4v) to a DVD+R-DL disk (Sony brand). I am not trying to break any copy protection - I just want to back them up as data files so I can archive them and make some more space on my hard drive. Every time I try to burn i get an "illegal sense error", I have made 4 coasters already. I tried Toast 10.0.6 and 10.0.8. I am running Mac OS X 10.6.4 on a 15" Macbook Pro, 4 GB RAM, 500 GB hard drive.

 

The Macbook Pro is up to date with all of the latest software and firmware upgrades.

Good luck getting a response. I asked the same question a few days ago:

I don't know the reasons for the problem you're having. You might try choosing Save as Disc Image and then burn the resulting .toast file to DL disc using the Image File setting in the Copy window. Some Apple Superdrives are also very picky about DL media. Verbatim discs seem to be the most reliable with the slot-loading superdrives.
