Just a wild stab, but I've had problems in other programs (ULEAD DVD
picture show for one) with the ID tags on MP3 files. You may want
to make a copy of an MP3 that's not working and remove the tags with
WINAMP to see if this helps.
(right click on the track in WINAMP, click file info, uncheck the ID
Tag boxes and save the file). Again, do this to a copy of the mp3
file or you'll wipe out title, artist, genre info on your original
mp3.
You should see the address of the header move (see mPEG info on the
file info screen). This may help.
