I Suspected as much.  Well that's a bummer.   Any ideas on what to do 
about the annoying audio issue?  It's not all the time, but when it 
happens, it's so irritating, nobody wants to continue the program.  It 
like blanks out (audio) every few seconds for a blip.
I'm really really hoping it's a reception issue, which i'll remedy soon 
with dual antennas.
