Currently, audio and video strips are synchronized based on data from media stream, which is nice, but this causes gaps between strips. This synchronization was implemented by moving movie strip position relative to sound, which doesn't make much sense for user which is mostly interested in editing video. Code was bit hard to read, so it has been simplified. Ideally video stream time would be easily accessible so synchronization could be done at any time, but this is not necessary at this point.
