No Recording to DVDRW

Downloaded and tried to use Backup to backup folders to DVDRW.

The drive appears to be accessed but no files written with compression on or off. The test function replies all is correct but after reading and comparing results of a test with the Help file i am not convinced the test function is working either.

I have tried and acheived a backup of a folder to my C: drive but retrying with the DVDRW produces the result explained above.

Currently running:

Microsoft Windows XP Home Edition
Version 5.1.2600 Service Pack 2 Build 2600
VIA Technologies, Inc.
AuthenticAMD ~1826 Mhz
BIOS Version/Date Phoenix Technologies, LTD 6.00 PG, 27/10/2004

Any ideas?
