    800MB CDs are not really standard and work only in certain burners. Do you know that your drive supports this size of media for sure?

    Because 800MB is not standard (and I guess not officially supported under Nero), you'll have to enable "Overburn". Open up Nero. If you're using Nero Express, click the 'Configure' button. If you're using Nero (regular), click 'File' and 'Preferences'.

    A window will pop up with quite a few options. Click on the "Expert Features" tab and enable "Disc at once overburning". Change the time from 80 minutes to 90 minutes.

    I think you'll only be able to write to these large discs using 'Disc At Once'. This means you cannot use these discs for Multi-session or maybe even 'Track at one' CDs. So when you burn CDs, make sure the Disc at once option is checked.

    90 minute CDs have terrible compatability with most drives. Infact, I've heard many negative things including possible damage to CD burners and readers that do not support them. So best of luck. :)
