Paul - Perhaps it depends on where you're located on the globe, but the info I have indicates that the +R disks are better for this. I have been successful at making other useful video DVD's with these disks but their file sizes were only about 1 GB, so I never ran into this capacity problem before. The problem stills stands. Why is there such a discrepancy in capacity advertised vs capacity "measured", and why is it so different between OSX and WinXP OS's?
