had a problem with some of the movies. it seems that FCE got confused over which audio render files to play, so everything had the wrong audio even though the original files played correctly. we deleted all render files, rerendered a small portion and it seemed to be ok. now the 2 hour exports for 2 minute chunks begins again. only about 5 mov files out of the entire month worth of output were effected.....estimating a total of 10 hours of export time will be needed
