When I record using RealJukeBoxPlusV2 (win98),
the resulting .mp3 have an ID3v2 tag in front with
some binary info that confuses the Empeg car player.
Uploading with emplode seems to avoid the problem,
but uploading with emptool results in a front panel message
of "invalid mp3 format" when attempting to play such files.

Thus.. I now strip off all ID3V2 content just as a matter of course
(the binary attachments confuse other players as well,
and lots of mp3's have embedded binary images etc..).
