I've got three or four short videos i'm stringing together ( has worked many times) they are all the same type of file.

Durinf the editing process, i

, trying to cut out the dead areas. I can get through about 3/4 of the string, then the whole thing freezes up. I can SOMETIMES go back to the begining, and go through all the edited parts, and it still freezes up at about the same place. Its NOT between two videos, it right in the middle of one.

 A few time a little box popped up saying this was taking" longer than expected, do you want to quit"

Heck no, it took me a long tome to set all this up.

Any ideas?
