It works for me.
Left-click on the horizontal hours list (to the left of the Now button) to set the start of the EPG display, and it defaults to a 5-hour span. Right-click to select an end hour and make the span less than or greater than 5 hours (8 hours max). Once the span is set, it is retained through further left-clicks.
My default is a 2 hour span, as set in the "Grid-style EPG Hours" setting within the webif "EPG Settings" section.Thanks for the clarification BH.
My default is an 8-hour span and it will not display any more than that when I use the right-click option which is why I thought it was not working.
It will, as you rightly say, show a reduced time span.
