When I want to change channel in ProgTV using Up and Down keys, it always crash. If i choose the channel from channel list it works. Also channel changing using Up and Down works in ProgDVB. Any solution? Thanks

Here is log (open ProgTV, change channel - crash): 16:49:46.990 - Start logging...

I had the same problem. Try enabling timeshift. It worked for me.
