Whatever you say, but the plain fact is, the same ISO file on the same Win 7 PC, the same Verbatim discs and the same burner works with the earlier version of ImgBurn every time, and fails with the later version very time. Must be a coincidence then!!

I successfully burnt a couple of large (24gb) bluray ISO images using ImgBurn v2.5.6. When I upgraded to 2.5.7 the burns consistently failed with 'Unable to finalise -incompatible format' (sorry I didn't keep the logs). This happened 5 times in a row, using Verbatim bluray discs, LG burner, tried different write speeds, made no difference. I did notice that despite the error, I was able to play one or two of the blurays. I un-installed and then re-installed v2.5.6, and now I'm able to burn successfully again. I don't really need any support as I'm quite happy now that its working again, but if you'd like me to investigate further, please let me know.
