Norton Ghost DVD writing problem

Hi,

I have Ghost 7 (came with Systemworks 2004) and am trying to use it for the first time. When it gets to the PC DOS screen and starts to write it only writes a 32 kb file on each DVD before asking for the next disc to be put in and so on.

The Toshiba DVD drive is listed as compatible by Norton.
I am using new DVD-RW discs which work fine on the computer with other applications.

Any suggestions?
Thanks

This is right off their site:

Ghost version
The only versions of Ghost capable of saving directly
to or restoring from DVD are:

Symantec Ghost 8.0
Norton Ghost 2003

In other words although you can use DVD-Rom with version 7 you cannot burn directly to a DVD
