Erasing DVD-RW

[richsm11]

I hope I have posted this tho the right forum.
I use DVDRW's to burn test DVD's of my daughter to ensure they play correctly in my standalone.
I have erased some DVD-RW using Nero 6 & now I cannot access the disk's at all. Whenever I try to burn them any burning app that I use refuses to recognise the disk.
If I right click on the drive (a NEC ND1300A) the machine locks up for @30 seconds & then does not give any info.
Please can someone help as I feel a complete idiot paying a DVDRW price & only being able to use them once therefore ultimatley getting DVDR's
I get this problem on more than 1 manufacturers media that IS compatable with my burner so that is not the issue.

No joy I tried both full & quick erase to no avail.
Is there any other way?
