Those are the inbuilt EPG reader options. They do not show what or how you are using to obtain the EPG.
From your logs, you are using the OpenTV EPG downloader.

The advice is to disable the Freesat EPG reader when you are using the OpenTV EPG reader to avoid a clash.
With regards to the Huffman conversion errors, there were a few recent commits on utf conversion, you will probably have to wait until 6.2 013 for them. I am not sure if they made it into 6.1 012. Might not be related.
However, you issue seems to be when playing back movies and stopping, so not directly related with EPG. Not many people use Timeshift automated, and it varies based on device drivers, so that is an added complication.
P.S, for taking screenshots and not having to worry about reflections from the TV when taking pictures, see here:
