Movie File Sizes

Video stream (elementary stream) doesn't require those overhead data for playback correctly. TS/PES header are required for multiplexed stream, those are not used for video decoding, so I subtracted those rate. If the overhead asumption is really correct, that number will fit near the actual video file size directly coming from video encoder. If the overhead is not considered, we never get correct video file size. Anyway, if the lossless audio codec or PiP stream gets included in muxed stream, we have no way to assume average video bit rate any more...

"Ave.V Rate" in the table I posted is intended to stand for video elementry only. If you don't like this way, you can pick your number as you like.
