Question about the "Time:" value displayed as a media capacity . . . in ImgBurn Suggestions Posted May 4, 2007 The problem is that MPEG2 is variably compressed. You can have a full DVD-5 that has any where from 60min to 180min of video. It also depends on what type of audio you use and other factors. I also think that your SP definition will vary between hardware and software. I think it would seem more confusing to some users to see this method. At the same time, the amount of 44.1k 16b CDA audio I can fit on a DVD has much meaning either. Maybe just don't show the time for anything other than CD?
