Phat may be right to some extent. How fast will the cd rom unit in the player be? How long will the unit take to encode it? What encoder will be used to encode it and at what bitrate? I see ATRAC3 on some of the pics, maybe it will only use that. Will you be able to listen to music off the HD while this is going on? How much storage does a memory stick have? 128MB? If so, thats a lot of trips back and forth to the computer to load the player up with music.
