Strangely enough the TV appears to accept an analog signal on HDMI1 but I'll
be darned if I can get a signal into it... just to be sure I was dealing
with a legit signal I unplugged the audio from my satellite receiver and
used that as the analog input and still nothing...

"You can forcefeed the driver a slightly modified EDID block with the audio
flags disabled.  Check out this page (http://analogbit.com/node/23) for
instructions on how to do so, and a copy of the program to modify the EDID
block."

How does this apply to the new NVidia driver 180.35 and is anyone
successfully doing it? Does that just tell the TV that there is no digital
signal over HDMI then I assume it would them "turn-on" the analog ports on
the tv?

The other thought I had was combining SPDIF with the DVI output from my PC
and simply supplying both audio and video over the HDMI output of th ePC,
can that be done?

Thanks,
