Hi,
How can I burn 900 MB CD with Nero or any other program please?

Can't you just set Nero to burn a DVD and not a CD?

If you set it to ask for a DVD and put a 900Mb CD-R in, what does it say?

nero allow us to overburn... there are option to overburn cdr
just depents on ya cdr and cdr burner....

When you open Nero Burning Rom, under file select "Preferences" then "Expert Features" with in expert features you can set the amount of minutes to burn.

700 MB = 80 mins
800 MB = 90 mins
900 MB = 100 mins

Your burner also has to be able to overburn, Most do, some dont.

As far as I know the only way you can do that is to use overburn but i have never had any sucsess it.

However this may just be bad luck on my part.

In general, overburn is about 715mb for me ...
I have bought some 100mins (900mb) cd-r's last year, they work, but not really compatible will all cd readers and not all recordes support theses too ...
