You have to be on the same network as your DirecTV receiver, and not all channels are available. I'm not seeing the pay movie channels, or the local channels, which are all a matter of rights with the owners of those channels. I counted 38 available channels for streaming, including CNN, Fox News, National Geographic, FX, History Channel, Discovery and many more. You can watch the video in a window hovering over the program guide, or watch full screen.
This new update also allows you to change start and end times of a recording if you think a program time needs adjusting. The app has also added an option to set parental controls on your receiver from the iPad.
Other TV providers, notably Comcast, have been working on streaming live TV to the iPad. The app is free and requires iOS 4.2 or later.
