Welcome:). First, you have to do your kprobe scans at 4x scan speed, the forum standard for comparison, so rescan and repost. You should also post a Nero InfoTool system scan in your next post. Save as .txt file and attach using the 'manage attachments' button in the 'go advance' reply window. Also, what brand name were these discs sold to you as? I believe there are some fake TY's going around, and you may have some. As much as I would like to make some guesses, I/we really can't make any suggestions until you provide the proper info for us.
