Ok, so I had a problem with my old rewriter as it was recognizing blank DVDs as CDs and so I got a different DVD rewriter and it is doing the same, so I think it's a BIOS or jumper problem.

What should I set my BIOS settings to and what should I set my jumper settings to? Many thanks.The BIOS won't cause this, and the only jumper on new optical drives is for the Master/Slave setting.
Can you provide us with more information about your system so that we can help you sort this out?Sure, what would you like to know? It's a PIONEER DVD-RW  DVR-112D.

What OS are you running?
What service pack is installed?
Are there any yellow or red FLAGGED devices in Device Manager?
What DVD/CD burning software are you using?OS - Windows XP
Service Pack 3
No flagged devices in DEV Man
I'm not using any DVD/CD burning software at the moment, I removed them all before I installed the new rewriter. I was using Cyberlink Power2go.This was in regedit:

Windows will show it according to what disk was used in it last...

Again...how is it HOOKED up inside the machine ? ?It's connected to the HDD.If there is another IDE connector you should use it...

If not the HDD should be jumpered master with the DVD as slave and cabled as follows:

MB===========================Master=========Slave.

But i doubt this is a jumper setting as Windows is showing the drive.
