This is because the recorded files have variable bit rate (VBR) and they
have no VBR header (Xing or VBRI). Thus the player doesn't know how long
the song is.

Winamp usually calculates the correct time, but it may have problems if
the sampling rate isn't 44.1 or 48kHz. Rockbox and the original Archos
firmware will think it is a CBR file and calculate the song length based
on the first encountered frame in the file.

Rockbox will add Xing headers to the recorded files, but not until I can
find the time to commit it to CVS (it is written, but not tested).
