2006-01-19  Martin Soto  <martinsoto@users.sourceforge.net>

* gst/mpegstream/gstmpegparse.h (struct _GstMPEGParse):
* gst/mpegstream/gstmpegparse.c (gst_mpeg_parse_reset)
(gst_mpeg_parse_process_event, gst_mpeg_parse_parse_packhead)
(gst_mpeg_parse_change_state):
Make timestamp adjustment somewhat milder. Actual timestamps are
now sent unmodified unless an actual gap is found in the
stream. This should fix time display when playing most MPEG
files.
