I have been successfully burning with ImgBurn using this media. All of a sudden I get a Power Calibration Area Error on every single attempt.
I read somewhere that the DVD firmware could be upgraded and I found a site offering a SC02 firmware download which it said ws for the TS-H652M, however when I tried to run the upgrade it said that it was not compatible with my drive.
So I am still no nearer to finding out why I can no longer burn videos to disc. Something must have changed, but I have no idea what. Here is my log (I cancelled this burn after two write attempts 'cos I know what happens next):
