Hey there, yesterday on christmas i got the nwa3000 and am damn happy with it, i had already heard about the problems and everything and was fully aware of the baggage with it, but damn it looks hot lol so i got it. Anyway, i got it up on the PC and connect player was being a bitch so i closed that and just used sonicstage importing all my music onto the walkman. It went fine, but found out i couldnt rate any tracks or anything on the walkman so i was pretty pissed. Anyway after a day of playing and that carrying on today i got CP fully working, and its a beast, its real nice and now it transfers songs absoloutely fine. So today i put it all into Connect Player, formatted the walkman and initilized it. And then transfered all of my MP3 music collection (1500 or something songs) onto it. Took less than half hour it was great. and sounds amazing. But my main question is, all my music is in mp3, and on the walkman when i go onto a song and select detailed information on a song it says its MP3 there too. But when i connect it to the pc and look at it in windows, all the files on it are like this: #####.oma and i cant find any mp3s on it. So what are they in, mp3 or oma?
