gmanhdtv ... thanks for posting. The more the merrier
I guess that we are going to have to do some more debug to determine what we think is the problem.
Last night I did rerun WMC setup on my #2 HTPC (Windows 7 Pro/WMC/Hauppauge tuners) and Channel 2.1 did come online. But tonight at 1800, 2.1 is down again. On WMC #1 2.1 has been down since sometime around Thursday. My Zenith HDTV receiver (not a WMC computer) is working OK.
I can still contact the WESH engineer if we have any other suggestions as to what he can try. He indicated to me that he had numerous computers with USB HDTV receivers and (I think) a Homerun, and none were having problems.
I hope to run some test routinnes tonight ... but don't hold your breath.
