Why overburn????????????
i bought a local DVD named FirstChoice with 4.7 GB space
i have burnt it upto 4.5 GB with no problems using Nero Ultra Edition
And 137 MB free space is still available..
U can do one thing .........
set the limits of burning(THE green ,Yellow and red size indicators to a higher level
this will stop showing u the warning messa ge
I also burnt 4.89 GB on another disc and its working fine!!!!!!!!!!!!!!!!
