I don't know when it happened (I caught this after upgrading to the svn trunk) but there is a mismatch of commands for controlling the mp3 player in the IA5 web and mp3_winamp.pl
 
The IA5 controls is RUN?Set_the_house_mp3_player_to_ 
but the mp3_winamp.pl command is Set house mp3 player to
 
Changing mp3_winamp.pl line 75 to read: Set the house mp3 player to  will allow the commands to work from the IA5 web pages. 
 
Can someone with write access make this correction?
