Good day folks, So I was just about to burn Windows Home Server 2011 to a disc, and I mounted the image in Disc Utility. It waited for me to insert a disc. I put in a Memorex DVD-R (15x 4.7GB) and it started burn then immediately switched to finishing burn and said writing failed. Can anyone confirm that these discs work in Lion, because I have a 100 spool of them, and I'll sell it if they won't work because my Macbook is the only system I burn due to the ease of use. I have heard things in the past about the differences between + and - R but I've never had a proper understanding of their differences, other then.. some systems support both and some don't. So if you can share some knowledge on that, that'd be fantastic!
