you can see catch up symbol while playing channel, press info button and you will see play button inside of almost complete circle symbol before TS so press right arrow and pick up previous program that you want to watch and hit ok.
what error do you get?
do you have any other version to install and test?
where did you downloaded it from? try to download from different place and try again
and I accidentally deleted moms favorite list many times while experimenting and had to setup over and over which was headache and now I can do it freely as I can restore once I messed up.
