Unable to write DVD .. not enough space issue

Hi

I am using NEro 6 software for Burning DVD.
I am unable to write DVD as it gives error… Not enough space on the disk.

In the hard drive where i have installed the XP OS , free space is just 1GB but it says requires 3GB free space…

Is there any way that i can map the space to any drive other than the drive where OS is installed… bcoz i have free space in other partitions…
Cant i make nero to use the free space from other drives???
Please give inputs…

You need to go into Preferences and change the Cache setting. Point it to another drive.
