+ *
+ * dxr3 video and spu decoder plugin. Accepts the video and spu data
+ * from XINE and sends it directly to the corresponding dxr3 devices.
+ * Takes precedence over the libmpeg2 and libspudec due to a higher
+ * priority.
+ * also incorporates an scr plugin for metronom
+ *
+ * update 7/1/2002 by jcdutton:
+ * Updated to work better with the changes done to dvdnav.
+ * Subtitles display properly now.
+ * TODO: Process NAV packets so that the first
+ * menu button appears, and also so that
+ * menu buttons disappear when one starts playing the movie.
+ * Processing NAV packets will also make "The White Rabbit"
+ * work on DXR3 as I currently works on XV.
+ *
+ * update 25/11/01 by Harm:
+ * Major retooling; so much so that I've decided to cvs-tag the dxr3 sources
+ * as DXR3_095 before commiting.
+ * - major retooling of dxr3_decode_data; Mike Lampard's comments indicate
+ * that dxr3_decode_data is called once every 12 frames or so. This seems
+ * no longer true; we're in fact called on average more than once per frame.
+ * This gives us some interesting possibilities to lead metronom up the garden
+ * path (and administer it a healthy beating behind the toolshed ;-).
+ * Read the comments for details, but the short version is that we take a
+ * look at the scr clock to guestimate when we should call get_frame/draw/free.
+ * - renamed update_aspect to parse_mpeg_header.
+ * - replaced printing to stderr by stdout, following xine practice and
+ * to make it easier to write messages to a log.
+ * - replaced 6667 flag with proper define in dxr3_video_out.h
+ *
+ * The upshot of all this is that sync is a lot better now; I get good
+ * a/v sync within a few seconds of playing after start/seek. I also
+ * get a lot of "throwing away frame..." messages, especially just
+ * after start/seek, but those are relatively harmless. (I guess we
+ * call img->draw a tad too often).
+ *
+ * update 21/12/01 by Harm
+ * many revisions, but I've been too lazy to document them here.
+ * read the cvs log, that's what it's for anyways.
