There are literally thousands of free to receive signals on C and Ku. You use a C/Ku receiver to move the dish and skew the LNBs. But you use splitters and DiSqe switches and take the signals from the C and Ku LNBs to a new DVB receiver.
Each transponder that used to be dedicated to a single analog standard definition channel now carries dozens of standard definition or high definition MPEG compressed channels. And while some may be encrypted, many more are not. And that includes most sports "back hauls".
One advantage is that these signals are the very best looking MPEG available. Because, in most cases, the HD MPEG signal is going to be decompressed to analog HD, have a logo stuck on it and be recompressed, it has to be very nigh quality to start with. An excellent OTA HD signal can be 19.2 Mb/sec, though usually limited to 12 Mb/sec so they can have a weather channel. On your local cable channel, it might be reduced to a 6 Mb/sec QAM signal. But the DVB signal may be as much as 35 Mb/sec!
