For those missing the "Live TV" button, I think hitting the Exit button on the DirecTV remote accomplishes pretty much the same thing.
The guide is better on Dish. Dish can do 3 hours instead of 1.5 (a feature I really miss, seeing all of primetime on one screen) and can show extra channels if you chose to turn off the picture-in-guide. Simple features that make the guide much more user friendly.
those are two good options :upJust press the PREV button and it goes directly to the live program. Hit PREV button again and it goes back to the recorded show directly where it was when you switched to live TV (no need to pause ahead of time).
