hi
please take a look at these thread
(i dont want to post this again)
viewtopic.php?f=14&t=91161
the mpg decoder / codecs are outdated in vlc (even in latest nighly)
i think after 18+ month an update would be good
so vlc will be able to play the 3 mpg files too
i don't know how much work is needed but
i thought vlc and mplayer will use same ffmpeg codecs
so just updating mpg codecs should make the 3 files playable...
