Am I missing something?
I own Toast Titanium 5 on CD and have updated it in the past. BEFORE the update suite package that you were referring to I already had version 5.1.2 of Toast, 1.5.1 of Spin Doctor, etc. It seems that the only app that seemed to be NEW is a carbonized version of Magic Discus (which used to be Classic only, I think).
However, Roxio lists on it's download page Toast as "Toast 5.1.2 Titanium update (Rev 2)". Is there a Rev 2 of version 5.1.2??? If so, then perhaps it is new. But why not just call it 5.1.3? Me confused.
