New Member
Hi guys i'm new too the forums. I using Windows 7 already 2 weeks, and found problem with burning dual layer DVD.
It was successful before I used Windows XP and NTI software. Now it is always fail. By my view disk not finalizing. I tried to burn with NTI, and with Windows 7 native burning software - failing with error: bad request. Any suggestions?
