hey people this is my first post ever, i was really encouraged to join this forum after i was totally unsuccessful in transferin even a single song to md player. i was really excited when i bought this player, but my expectations were broken completely when i kept on tryin but failed misserably. i jus bought this player 4 days ago, it had sonic stage 1.5 version wchich i upgraded to 3.1 as guided by sony support guy. i even contacted them but found no solution. i tried many different songs but i keep on getting the annoying message that "Cannot convert the specified track. SonicStage does not support the file format of the track." i got around 5 gb of songs on my PC's hardisc and all of them are either mp3 or wav format but still i cant even transfer a single song, my PC is P 4 and i'm using windows xp home edition i guess with service pack 2. i even tried real player, but i get the same message that format not supported.i also tried all the updates. please help me here, please suggest any alternatives.
