Program schedule indication.

When energising, 80% of programs in schedule indicates "no information". Doing 2 or 3 automatic channel programming solves 40% of the problem. This means recording cannot be set as the program schedule shows " no information". Several emails re this issue every time results in a reply indicating how to unplug the power and aerial and reconnect, which is not the problem. It also does not help to phone the call centre as they are totally clueless. The latest is that they sent me a list of error codes, which is not applicable. What a poor show - absolutely no technical support or knowledgebase.
