I just checked a new disk 4/5 (just removed the plastic), it seems to be 4,25GB

Something in that log don't match your saying. The log is correct. I am 100% sure the disk is Dual Layer, verbatim original. I didn't pay attention to disk size because of the XGD3 (Xbox Game Data 3) particularity: it is 8.7GB (0.2GB more than a DL). So, various guides recommend to truncate overflow data (that is the same for any disk). This is the reason I have not noticed that my disk is 4.25GB. I realize that is no longer a problem related to ImgBurn but I would be grateful if someone can tell me why my computer considers only 4.25GB of the 8.5GB. In the past I have burned this kind of DVDs with this drive.

The posted log shows that you use single layer discs. I checked in Computer and the available space on disk appears to be 4.25GB. Could it be a system error? The disk Is Verbatim DVD+R DL 8x (Double Layer, Double Couche), I always used them with Windows Vista.

Sorry I forgot the log Yes, I tried all speeds from 1x to 8x (including MAX and AWS) I also tried with the OPC setting, but I get the error: Optimum Power Calibration Failed!

Hi sorry for the new topic but I can't find a solution to my problem. I read this topic http://forum.imgburn.com/index.php?showtopic=8000 And I followed all the five targets but I still have this error, that appears after the buffer is 100% and the writing didn't begin.
