What is the particular advantage of EDL, versus something more standard: http://www.w3.org/TR/SMIL/ http://en.wikipedia.org/wiki/Synchronized_Multimedia_Integration_Language ?? Mplayer (and thus http://en.wikipedia.org/wiki/K-Multimedia_Player , smplayer, and gnome-mplayer) supports SMIL although the support is rudimentary. SMIL and other means of setting clips&playlists is available in the flash-based 'jwplayer' http://www.longtailvideo.com "Attribution-NonCommercial-ShareAlike 3.0 Unported" ( in action: http://nielsmayer.com/xwiki/bin/view/Macros/JWPlayerJSPL_Test and http://nielsmayer.com/xwiki/bin/view/Exhibit/NPRpods3 (work in progress) ). The other issue w/ doing it "in the player" is how well do the given players handle a playlist. Most of them, even if accessing the same media in different cue-locations, do not do a very good job with going through "clips" with seamless transitions between the clips. However, it's readily possible , with a bit of pre-buffering and pre-fetching that allows seamless synchronized playback .... just a small matter of programming...
