MYCOMETG3 I have confirmed Toast 8.0.3 now runs properly with mp4vDecoder. Obviously, it was NOT mp4vDecoder issue. (Version 0.7r2)
MACSOLU Should this be used instead of Perian and Flip4Mac or in addition to those two Sys.Preferences? (Version 0.7)
MYCOMETG3 Try remove DivXdecoder.component, and check if it helps. (Version 0.6.7)
FLU33 prevents toast titanium 8.01 from starting up. (Version 0.6.7)
