"You have inserted a blank DVD..." So I burnt my video project to DVD using DVD Studio Pro on an iMac at Uni, but when I insert the disk on my MBP at home, it reads it as a blank DVD with nothing on it. I have tested the disc(s) on other laptops (PC and Mac) and my DVD player, and all play the video fine. I use my laptop for everything so this is very annoying for me. Do you guys know how to fix this problem? ---- edit My MBP reads other discs fine.
