I used ImgBurn and the files were written to DVD fine. But suddenly these errors started as they used to be in Nero. Here's are some screen shots. Please help me. Tel me what wrong did I select while writing DVD. The DVD dtive in my laptop is also in the screenshots uploaded. I've also uploaded log files. Please take a look and help me please.
