When I use DVD2OneX and set the output to DVD+/-RW and burn it on Toast, I get an insufficient room message (yes, I have set Toast to Data). The message is "2301433 (4.4 GB) needed. 2298496 (4.4GB) available" So I have to set a custom size. Without experimentation, I found that 4400 MB works. Any idea why the default output from DVD2OneX is apparently a little bit too big to burn on a standard DVD? What is the maximum custom size I can select and burn it on Toast?
