Hey all, I haven't read any posts on here with similar problems but there are loads on the Apple Support board about similar situation. They couldn't find much of a solution. I have tried using toast and disk utility to burn on my DVDs (dual layers to be exact) but haven't had much luck since all comes up with medium error? I tried different brands/batch etc, but still the same problem. Did the whole permissions checking, didn't help... It burns CDs alright though and DVDs, just not DL Curious if anyone here have similar problems or have solutions etc? Thanks!
