Hey, but it's not true that it can't encode mp3's! I mean, I have the same problem with MZ N-510, it won't transfer mp3s onto the minidisc and gives me the sam message, but when I use another computer, it works quite well! A month ago I was able to transfer any file onto the disc (of sourse it would first encode it to atrac) but now it just says that it doesn't support mp3 format!! I think this is a sonic stage bug, ahhh it's full of bugs! And another thing: why can't I COMPLETELY uninstall sonicstage?! Is there a patch or something that would fix the support for mp3? Thanxx...
