Quicktime MOV broken in Snow Leopard QT ver 10

I stitched together some qt movies using QT-pro v7.x.
Now QT 10 player and QT 7 is asking for the components I stitched together in a combined movie now.
I threw away the individual MOV's. Getting "the movie could not be opened. The operation couldn't be completed. (OSStatus error -128)" & "searching for movie data file".

These movies(& files?) were on the drive converted to Snow Leopard!
