Xbox 360, Sharing music.

I went out and bought the 360 yesterday, and today I'm trying to get my music to hook up through my computer to the system.

I can choose the music on the 360, but when I try to play i get error code 19-04-80004005. I can play my Videos and Pictures just fine but with music it wount let me.

Any help is apperciated.

either one of the two probs that i have of right now

1)you need windows media player 11+ with newest version of media center to transfer music like that or...

2) music file ext not the right format atm i think the 360 can only play windows formats and mp3s since half my ipod songs work half being from itunes(dont work) half from other sources(mp3 and work)

i hope this helped also if u play GoW gears of war add xX TeamKill
