I recorded some gapless stuff using "lame --nogap" and uploaded it to the player. Without VBR headers, it played back flawlessly, but the displayed times were wrong, and FF/REW/seek-tool didn't work exactly as they should (this is expected, of course).

So I used the mp3info program out of Florian Maul's mp3lister to add VBR headers, and re-uploaded. Now the timings are correct, but there's a tiny hiccup between tracks. It's smaller than when I had encoded without --nogap, but it is perceptible. I'd guess it's around 50ms or so, but I'm no judge of that sort of thing.

Is this somehow my fault? If not, is it likely to be fixed, or do I need to make CBR (or ABR?) files to get real gapless playback?
