A couple weeks ago I noticed my MythTV DataDirect (Zap2It) go out of sync. There are a lot of shows not recording at the right time. Im using "Comcast - Salt Lake City - Rebuild (for 84058)" on Zap2It. I'm not sure if the change is with Comcast, the Network, or Zap2It. Has anyone else noticed this, and what change should I make to correct it?
