Portland, OR 97229 - New install w/Hauppauge 01657 Dual HD: Program Guide "Unknown Airing"

This is a brand new install of the latest Plex & Plex Media Server on Windows 10, with a Hauppauge 01657 WinTV Dual HD device.

  • Problem:
    Guide shows “Unknown Airings” for most selected channels
  • The lineup/EPG Location name:
    Local Broadcast Listings 97229
  • Your country:
    USA
  • Postal code:
    97229
  • Region/market/city,state:
    Portland, OR

I have only 6 of the 45 available channels selected.

During Guide refresh it says “1238 airings” and seems to complete normally

After refresh, the major networks CBS, NBC, ABC all show “Unknown Airing”, while CW and CWDT2 have program data.

I have refreshed the guide multiple times.

This seems to have corrected itself partially overnight, except now my local station KGW (Portland, OR) shows up as KSL (Salt Lake City). How do I fix this?
