I also experienced some odd behavior with Imgburn 2.2 and burning 360 DL media. I'm running Vista Ultimate and using Matrix 2.4x (oem Ricoh) certified DL discs. I had good results using the XBC burn engine. I also have Nero 7.7.5 installed. However, I decided to install Imgburn 2.2 as I prefer that as my burning tool. I adjusted no settings on Imgburn except unchecking the verify option. After install, my next 10 burns produced 8 coasters, all failing with a media sense error. Three failed while finalizing track, 3 failed right after lead-in, and the other 2 failed in the middle near the 50% mark. One of the discs I thought burned properly actually did not record properly. I kept thinking it must be the cheap media I purchased, though this was an extreme number of problematic discs. I realized that the only thing to change was the installation of Imgburn. After uninstalling Imgburn and rebooting, I produced 3 discs, all perfect. Imgburn must have somet type of effect as the coasters were produced even when I selected alternative burn engines such as XBC or Nero. There is definitely some type of correlation here, perhaps a dll? A correlation definitely seems to exist. I eventually would like to use Imgburn again but I would need to have this problem examined. Is there any type of troubleshooting steps I can take to see what may have been the cause of the problem?
