The internal audio mode is the only setting on fxtv that I can hear a faint 
audio signal after playing with the mixer software and increasing the  
sound level on the speakers-- it's barely detectable from the background
noise-- hey, it's a start.  I have been reading the documentation
at the Hauppauge WinTV web site and they mention that 2 mixers come to
play-- one associated with the sound card (which is easily accessable)
and one specific to the a Hauppauge WinTV PCI Card.  My investigation now 
is centered around accessing the mixer on the WinTV card.

Last night I grabbed the xmradio from the ports however as I invoked
it on the command line, it locked up my system hard resulting in my
power cycling it.  I also noticed the my system has locked up w/fxtv
and mplayer.  


It's an interesting learning experience.  I'm hoping to extend this
and add Mythtv or play with some shell or perl scripting.
