Is it possible for me to play all those file format that we usually get online using windows XP MCE??? I mean using the remote and everything to play all those files??? Can we add codecs to the nice media center???

just install a codec pack

So windows xp MCE is just like the other windows media player??? where i can just install like stormcodec or any codec pack and the nice littte place will play everything???

yes..

MCE is based on XP Pro with some feature removed and added Media Center

I mean can the media center support those external codecs... I don't want to be playing my stuffs on media player classic or VLC...

Any good codecs to recommend???
