I use Nero 6 because my OS is Windows 98SE. I've made some MP3 CD compilations using Nero in the past and I save these as .NRI files. The problem is that where the original compilation fit under the 700 mb limit and could be burned to 1 cd, when I try to burn the same compilation again, the file size has expanded to over the 700 mb line. There has been no changes to the files, nothing deleted or added but the compilation will no longer fit on 1 cd. Has anyone else ever had this problem with Nero?
