One thing I’ve just found which some may not know about is how to use a form of the backward EPG on the iPlayer App – this is different to the website which is easier to use and more obvious where you just go to TV Guide and get straight there.
On the left of the iPlayer App select ChannelsBBC1 etc, then with the down button go down to the bottom (past all the useless bumf) and select “Schedule”, this brings up an EPG of sorts for that channel.
This is nothing like as easy to use as the backward EPG, but does at least let you look back a week – searching by program name does not work well if you are trying to find say Monday’s showing of Bargain Hunt.
