Is this really an error. During boot, I get the following messages:

player.cpp : 385:empeg-car 2.00-beta13 2002/07/24
Prolux 4 empeg car - 2.1434 Jul 24 2002
Ucb: 0x4086d000
! mp3_decoder.cpp :1049:Failed to find valid sync after seeking to offset 9090

What does that last line mean? Should I concern myself?
