4 x copies burned succesfully at 4x, just hope they read OK in the target machines now. Excellent program btw I particularly like the hints when the user makes a mistake. Many thanks for your help today and I've hit the donate button

Many thanks - trying 4x now then the others..... So the dye may be the problem as CMC is on your not recommended list

A quick search shows that media can be the source of DL burning issues - Is TDK 8x +R regarded as a good choice? - I would have got Verbatim if I had read the post befoer but now I've got the 25 TDK's to use first. The problem I am having is burning from an ISO created with IMGBURN - tried twice and got the following. The drive is a brand new LG GH22 update to TN03 firmware. I haven't yet tried burning at a slower speed - could this help? This is the log, any help greatly appreciated! I 11:12:56 ImgBurn Version 2.5.3.0 started!
