Ok my problem is that advanced analysis seems to work randomly for me. For example, I tried to burn a backup of my scarface dvd onto 1 disk. The First time I used advanced analysis and it worked perfectly, except i messed up on the menus. So when I went to burn it again the tickbox for Advanced analysis was blanked out and I could not check or uncheck it (It was not available). I tried uninstalling, deleting all nero/ahead from the registry but to no avail. I know the first time it burned advanced analysis was definitely on because it took over 1.5 hours (usual dvd burn takes 40 min). When I put in the scarface bonus disc the advanced analysis becomes available again. Can someone please let me know how make this option available again?? I have no idea what is wrong with it and it is not limited to scarface (I tried with Shrek 2 just to check and the same thing happened). This only seems to be a problem for a few discs. Any ideas??? I am going nuts trying to figure this out. Ps. I am new to the forums!
