Toast Is Reporting Wrong Sizes For Discs

[MacGoddess]

I just used Toast 10.0.8 in the Video tab to add 3 videos which I wanted to burn to a DVD. At the bottom of the screen, there is bar where you can choose the type of disc and it tells you how much room you will need or have available once you drag the videos into the window. I have the DVD size selected and the 3 videos appear to total 4.11 GB with 283.3 MBs available. Unfortunately, when I tried to burn the DVD, I got a message saying it wouldn't fit on that media. So I saved it as a disk image. I then checked the size of the disk image and it was just over 5 GBs! Toast used to be more accurate but lately it seems to be screwing up with sizes. I have also had the problem where Toast will not compress the video DVD to a single layer. It lets me choose Single Layer but then it won't compress it.

 

I figure these problems may have something to do with Snow Leopard because Toast used to work fine but more and more I am finding problems with it. I have a fairly new MacPro and Snow Leopard 10.6.6.

This could be related to the fact that Snow Leopard now reports disk sizes measured in decimal powers (i.e. 1,000s and 1,000,000s). Leopard (and earlier OSXs) reported in binary powers (1,024 and 1,048,576 etc...)

 

For example: a nominal 500GB drive in Snow Leopard is reported as "499.97GB" whereas Leopard reported the same disk as "465.64GB".

 

Toast may not actually be behaving consistently or correctly?

When spanning multiple discs, Toast's calculations are all wrong. For example, burning 181GB spans 9 BD discs with 28.54GB remaining, which is more than one entire BD disc wasted (it should only require 8 discs). If I add a bit more content, the requirement jumps to 10 discs with even more wasted space!

 

SImilarly, spanning 87GB requires 5 BD discs with 29.5GB remaining, more than one entire BD disc wasted. The wasted space is spread throughout the disc set, and appears to be due to Toast's brain-dead manner of allocating files in precisely the order listed. In other words, if the next file on the list is 2GB and only 1.9GB remains on the disc, Toast wastes the 1.9GB and moves to the next disc.

 

I've reported this to Roxio but they have offered no explanation.
