Except when you do that, you also have to decrease the font ....
Its hard enough to read now.
I guess it depends on the size of the screen. When E* had the 3-hour guide I had no problem reading it on my 50" Panny at 8'. Looking at the pic that CSM posted, it looks like they have since reduced the time because they added the station logos along with the channel and put the program info on the right side of the screen. I now prefer the current D* guide to that new one from E*. I don't need the logos, so that is wasted space, IMO. But it may be coming to the new D* guide, right?
