Hello,

I may just be being a dumb blond but I have tried to burn onto a 800MB disc, but nero is only registering the cd as a 700MB. Could someone please help me with this problem, I am pretty sure that I have used 800MB cd-r's with this cd writer before but for some reason these aren't working!

What is the make & model number of the CD Writer?

Here's a link to a page that has 2 charts identifying CD writers that should detect 90min+ CDs

I've just picked this up from another forum (found using google)

"That's normal. Nero (and all other programs) will detect a 99 minute CD-R as only 80 minute (700MB). Just enable overburn in the setting menu "File, Preferences, Expert Features". Set it to 90:00 minutes. Then start recording. Nero will ask if you want to overburn. Select yes. Please note that not all recorders can do this."

It's possible that this is what you did before but maybe you reinstalled the app & lost the settings.

I refuse to edit this post any more. It's now my third edit as I keep finding out a little bit more.

It's been useful as I now know that my old liteon writer will write to 90min CDs.
