Help with burning a 900MB CD

Hi, after I finished burning a 900MB disc, i received the following error:

10/10/2003 11:40:38 PM error Write failed
10/10/2003 11:40:16 PM info Finalizing CD …
10/10/2003 11:40:16 PM error (WriteSector) Failed: Code 05 63 00 [Illegal request, end of user area encountered on this track

Could anyone please enlighten me what the problem is?
Another question, should I change any settings if I were to burn a disc larger than 700MB??

I received a message asking me to verify that I have put in a 800MB disc but I already did!! I ignored the message and continue with the burning. Is that the cause of error?
