FIRST OF ALL, PLEASE NOTE that 90 and 99 minute media will only be seen by the system as 80 minute disks, no matter what make or model of burner you have, but Nero will burn it to the 90 or 99 minutes, so don’t think your drive doesn’t support them just because they only show as 79 minutes 59 seconds.
You need proper 90 or 99 minute media. With the exception of Infiniti 80+, (which are actually 99 minute media) 74 or 80 minute media will NOT overburn to 90 or 99 minutes, and 90 minute media will not overburn to 99 minutes unless the disk manufacturer specifically state otherwise.
In Nero, go into the “file” menu and select “preferences” and “Expert Features” and enable overburn in DAO mode. Then set the maximum disk size to 89 minutes 58 seconds 0 frames for 90 minute disks, or 98 minutes 58 seconds 0 frames for 99 minute disks.
I recommend that you don’t burn the data directly to the CDR. Create an image first.
When you select burn, if you see on the burning screen a box “Close Wizard”, click on it and you will get the standard burn screen. The Wizard tends to stop you from selecting the correct mode and can stop you from burning 90/99 minute disks.
Select DAO mode for burning, then burn at preferably 8x (or less if your burner supports it) although you may have luck at higher speeds.
Nero will almost certainly put up a message saying the disk does not have enough space, then another one should pop up and should give you the option to cancel or continue using DAO overburn. Select continue using overburn option.
You MUST burn in DAO mode for 90 and 99 minute disks as you are overburning, which is not possible in TAO mode.
You cannot overburn using multisession as this uses TAO mode, so multisession will only allow 74 minutes on 74 minute disks and 80 minutes on 80 minute disks. You cannot burn 90 or 99 minutes using multisession at all.
I must emphasise that you must specify No Multisession and also select Finalise Disk. The disk MUST be burned in DAO mode.
ONE MORE POINT TO NOTE: Many CDRom/DVDRom drives, along with many home DVD players and car/home/portable audio CD or MP3 CD players will NOT read 90 and 99 minutes,and some wont even read the disks at all.
