My 921 has developed a new problem in the past few days. The info banner lags behind one channel when I switch channels. For example, I tune to OTA channel 19.1 then 39.1. The banner will show it is still on 19.1 but it is actually on 39.1. If I change channels to channel 200 it will now say it is on 39.1. Everything else works okay. It will record the correct channels. Soft reboots do not help. I will unplug the unit and reboot that way tonight. Has anybody else experienced this? I have the 213 software.
