Toast 10 size limitations

[IanC 0]

Toast 10, OS X 10.8.

It used to be that I could burn up to 4.6 Gb+ to a disc but recently my copy of Toast 10 will not burn files bigger than about 4.3 Gb.  I use FCP 7, Compressor & DVDSP to create DVD folders that I then burn in Toast.  Any thoughts?

Toast and macOS Finder calculate sizes differently.

One DVD ≈ 4,700,000,000 bytes = 4.7×1000×1000×1000 = 4.7×(10^9) = 4.7 GB (base 10, as macOS, since Mac OS X 10.6 Snow Leopard)
One DVD ≈ 4,700,000,000 bytes ≈ 4.3×1024×1024×1024 = 4.3×(2^30) = 4.3 Gibibyte = 4.3 GB (base 2, as Toast)
