Hi,
the mode 1 problem you mention is fixed in version 3.50.044 you can update by following the instructions mentioned in this post ..

with regards the mp3 playback this feature is no longer supported because most people have much more sophisticated free media players already installed on their computers (e.g itunes, winamp etc)
