CD-R/RW Drive model GCE-8080N

Hi all,
I have a Dell latitude C-840 with a DVD-rom as a fixed optical device and in the front bay a removable CD-R/RW Drive model GCE-8080N . It is working fine (x8) but when I insert a cd of 780 mega (90 minutes) my Nero (latest version) will only recognize it as a 700 mega (703 to be exact) and if I will try the burn command, it will tell me that there is not enough space in the medium and I have to abort. I tried to change the Nero config. but to no avail. I do think that it might be a driver problem (driver provider: Microsoft, date 7/1/2001, version 5.1.2535…0) or a firmware that has to be changed/updated (?)

Is there any solution to my problem ?

Any help will be greatly appreciated.

TIA, Isaac.
