My Mac doesnt recognise blank DVDs

Hi all,
A real conundrum;
My (brand new) mac doesnt seem to read blank DVDs. I went to system preferenes, CD & DVD to see the options there and I notice that I dont seem to have a drop down menu for what to do when a blank DVD is inserted. There is one for CD, but not for DVD.
My partner has a mac and there is a drop down option on hers.
Is there anything I can do or have I got a faulty mac?

Any help is much appreciated.

Do you have any software for writing DVDs installed at all? My mac itself doesn't mount blank disks, I have Toast, which does.

Which Mac did you get? Maybe you only got a Combo Drive instead of the Super Drive.

Click on the apple in the menu bar choose "About This Mac" and then press the "More Info.." button. What does it say under Hardware>Disc Burning?

Hi,
this is what it says in about my mac

MATSHITA CD-RW CW-8221:

Firmware Revision: GA0K
Interconnect: ATAPI
Burn Support: Yes (Apple Shipping Drive)
Cache: 2048 KB
Reads DVD: Yes
CD-Write: -R, -RW
Write Strategies: CD-TAO, CD-SAO, CD-Raw
Media: Insert media and refresh to show available burn speeds

so it looks like it doesnt burn blank DVDs.

Also, I do actually have Toast - that is actually what instigated me into this enquiry - I cant for the life burn my files on my computer to a blank DVD on toast - it literally will not read my blank dvd - it just spits it back out.

I presume that it will only work with blank CDs...?

By the way, I really appreciate your replies....

many thanks

Yea, it looks like you can't burn to DVDs. If you were supposed to get a Super Drive with the ability to burn DVDs, then you should call Apple.

Your machine doesn't have a DVD burner (writer)..

Your machine WILL: Read CD's.... Write CD's.... and Read DVD's.

It will not: Write DVD's.
