I've been using ImgBurn for over a year now with Sony DVD+R v1.3/16x disks and have had maybe 3 bad burns. However, over the past 3 days I've been unable to burn any isos at all due to a Power Calibration Error.

I've taken the following steps:
Upgraded my firmware
Updated ImgBurn
Tried different disks (both the same brand and different brands)
Tried different ISOs that have worked in the past
Enabled DMA
Tried moving the ISO to a different location
Tried burning at 2x through 16x

Nothing has helped and I'm getting desperate. Here is the log from my last failed burn:

Any help would be greatly appreciated.

Might be time for a new burner.

You might want to try with better media, such as Verbatim and Taiyo Yuden blanks. Also try with other burning speeds (with DVD burning slower doesn't always mean better).
