Galaxy S not working with Home Cinema set
I would say that this would be somewhat of a "driver" issue. It seems that your Home Cinema system does not know what your device is and it cannot connect to it. 

I would try seeing if there is a firmware update for the system (if it supports firmware updates). 

It recognizes the blackberry because they have been around for so long, and they probably use the same driver to communicate with just about any blackberry.
