I have a Sony Mavica MVC-CD350 which save an MPEG file for movies to a 3" mini cd. I have Tiger OS 10.4.5 with Quicktime updated, also. However, it can't open Sony's MPEG file, I get the terminal spinning wheel and have to force quit. I found a converter that I thought would work, but it required that the MPEG file be opened and saved with a different name, I can't do that. Does anyone know of a conversion program that will work for this problem?
