Found some pictures of your player at tomshardware.hu (why I can't find 
it in english I don't know).  From the looks of it you are right about 
the Sigma Design chip (at least 1 generation old).  Also, you might be 
interested in the uPCI wireless card as Sigma Design based boards appear 
to all use such a card (which is optional in some boxes).  Also, there 
appears to be an IDE target on the board.  This is probably functional 
if you want to add internal storage.
