convert it!!
that file is just too big really, plus although these players say "play anything" the reality is very different, some people are lucky with their files and they play fine some do not
its a case of get the player and see if it works, but that vob is too big anyway, i would convert it using VIDROP on this site to an xvid or something and reduce the file by half if not more
also visit
www.mp4nation.net/forums as that site has lots of info and users and themes for this player
cheers
