I tried burning at 8x with similar results (log attached). The MIDs are: Verbatim: CMC MAG. AM3 Memorex: CMC MAG-M01-00 I'd seen somewhere that ITunes can interfere with burning. I tried stopping all the Apple processes I could find but it didn't help. ImgBurn2.log

What do you mean by "same mid"?

I've mangled 5 DVDs thusfar (Verbatim and Memorex).. Log file is attached. ImgBurn.log

At first, I tried a Verbatim 16x DVD-R. I got various errors at the start of the burning process. Unfortunately, I didn't think to save that log. Just tried using the same ISO to a Memorex DVD+R. This time, the errors appeared at the end of the burning process. Here is the log: ==================== I 18:48:17 ImgBurn Version 2.5.8.0 started!
