I have good news. Despite the error message during the burning procedure, i inserted the DVD in my drive, and guess what ? The game is installed without ant problems, and now my daughter is playing with it!!!
Thank you both for your help, and mainly for the interesting info about MID. My next purchase will be verbatim.
As a conclusion, i still have 100% success with imgburn, and that's something very important for me. Keep up the good work.
