I was receiving channels just fine Analog and Digital channels until June 12th. Post transition, I am not receiving certain channels through WMC. I have a Hauppauge 2250 TV tuner with Windows 7 RC. My HDTV's built in tuner picks up all my previous channels just fine as does all my analog TV's with converter boxes. I have a HTPC set up for recording shows, I noticed last night one of my shows was not recording and discovered the problem.
I have checked the signal strength of the channel in question. I am getting a signal strength of 77-82 on my HDTV's tuner and 88-92 on the converter boxes. When I test signal strength via WMC it shows poor signal strength. I downloaded the latest driver
for Hauppauge 2250, I have scanned for new channels via WMC too. I have done everything up to this point.
