i got this player called GOM yesterday from this site. the thing is totally awsome. it runs flawlessly and comes with every codec you need including dvd. it has more tweaks and functions than you can shake a stick at, including custom image resize, tv image correction and a codec selector. i could spend a week just tinkering with settings if i wanted, but it plays perfectly already and it looks cool.
that site has a list of tons of other quality freeware. i also got a thing called rocket dock witch looks neat on the projector instead of the boring windows setup.
