Rewrote the mpeg1 system stream parser.
Original commit message from CVS: Rewrote the mpeg1 system stream parser. Fixed a motion compensation bug (was a bug on Intels site) Faster/Better/more accurate motion detection in the mpeg encoder Added an audio resampler (convert 48000 kHz to 44100 for example) does not work Fixed rate control in the mpeg2 encoder.
