I have a Sony digital video recorder and I put the files (AVCHD) into the Windows Live Movie Maker. At first the program didn't accept it (the scenes were gray boxes with a yellow triangle in the middle), but then the scenes showed up later and I could use the files! Now I'm trying to save it as a movie, and it starts and then at a random point in the progress bar, one scene is not accepted by the WLMM. Then the saving as a movie shuts down. How do I fix this to where I can save it as a movie without a problem?
