I set it to 4.0x and it did complete OK, using the same iso file as before.

That's not a good sign. 'MAX' = 8x. Try one of the other supported speeds. I do occasionally get this message on all my drives (5 different ones). I don't know if its related to a particular batch of dvd's or not. Since it always passes when I click the try again, I was not sure it meant any fatal error, although I also don't truly understand what it means other than a calibration of some signal failed, and then passed on retry . Or does it only get one attempt and the retry just continues? When using the 4.7 dvd's the calibration error does not result in a verify error, at least as near as I can remember. I will try setting the max speed to 4 or 6 next time I try a DL. Thanks for the product, it has been very nice to use with SVD2DVD to author disks.

I had attached the log to the earlier message, but I don't see any way to access it now from the message board. I believe this was the the second burn attempt. The first attempt was already overwritten before I tried to get it. ; //****************************************\\ ; ImgBurn Version 2.5.0.0 - Log ; Sunday, 11 October 2009, 18:31:46 ; \\****************************************// ; ; I 17:08:20 ImgBurn Version 2.5.0.0 started!

I use ImgBurn all the time, very successfully with single layer disks. I do not often use DL disks, but seem to have a lot of difficulty, not with writing, but with the verification.

Both failed in the approximately the same place (visually the same, but I didn't save the earlier log). The disks seem to work, but the verification does not succeed.
