hehe i went onto google define, and stupid me...i get loads about what toast is...the breaded kind... oh dear...
I found this on a site though i'm afraid:
"Toast 6 runs on Mac OS X only. This is basically an .ISO file. Sonic Solutions bought out Roxio’s consumer software division on 20 December 2004."
Found this though...dont know if it'll be of any use about doing it in windows:
I hope this helps
