Overspeeding Media Problem

Hi,

I have the GSA-H10N DVD rewriter, and am using the JL11RPC1 firmware (from TDBs). I am using genuine Taiyo Yuden DVD+R 8x media, which burn fine at 8x speed, however when I select 12x, using nero Burning Rom 6 (latest version) and try to burn DVD Video Files, it starts by caching the files, and gets to 3% and then does not continue.

I opened the firmware in Media Code Speed Edit, and for this media, 4x, 8x and 12x appear when the media is highlighted, in the speed indication boxes.

What is the problem that is stopping me from burning this excellent media at 12x with the GSA-H10N?

Many thanks for your suggestions. :slight_smile:
