How to change epg from 3 hrs to 1 1/2 hrs

--------------------------------------------------------------------------------

I found this great, with the 3 hour layout being so crammed and not seeing
much of the info, when switching to the 1 1/2 hour layout, you get more info
in the shows and makes it alot easier to read whats on. Here is how

Push the EPG button on the remote.

Now you will see the timelines have changed at the top of the epg showing a span of 1 1/2 hours
and the info for the shows in the guide will expand and show more info
