trouble burning to dvdrw

[whispersGhost]

hi

Open Solaris 05 -08

i am trying to copy an avi file 790 megs to a dvd rw disk.
Using CD/DVD Creator

And i keep getting a stupid error telling me to insert
a blank disk or only to use a compatable disk such as
DVD-R, DVD+R, DVD+RW, and DVD-RW

i had to erase it from windows to make sure it was empty.
And i still can not use write to the disk.

My Disks are all compatable with my drive as well.

Can someone please help me with this

Thank You
