You will need an LNB (the device attached to your satellite dish) with multiple outputs. It is not recommended to split one cable into multiple feeds.
Set Top Boxes require one satellite feed.
Digital TV Recorders require two satellite feeds.
As long as your LNB has enough outputs, you can have as many set top boxes and DTR's as you wish.
