Add simple edit list support to mov demuxer, it supports delay of audio and video tracks at the beginning of the file. E.g. video starts at 0.0s audio at 4.0s. It uses mplayers a/v-delay to achieve sync so please use with -framedrop for fastest sync. More Details in my mail to dev-eng from 2006-07-22.
