Problems burning at end of burn

I’ve been having some problems with Imgburn and I don’t know if its my burner, imgburn, dvdfab or dvd decrypter…

I previously had no problem burning, but all of a sudden i’ve been having troubles.

The device buffer fluctuates from 100 to 66 every 5 seconds.

I tried uninstalling the drivers for my burner, updating the firmware…etc., no solution.

I was hoping I could get some help from the forums…here is the log

Get some Verbatim / Taiyo Yuden media.

You could try cleaning the lense on the drive too.
