Catchup does not work - I can load a program from yesterday, but I can not change the time position within the program

Describe the bug
Catchup does not work - I can load a program from yesterday, but I can not change the time position within the program.

If I click on the EPG on the right, get all list of all the previous shows and click on one - it starts playing, BUT I can not wind it forward into the middle of the show or manipulate the currently played time beyond the few seconds of the buffer.

That is if I load "wheeler dealers" from yesterday on national geographic I can not skip to the middle of the show, there is simply no way, at least no obvious way to move to the middle of it.
