If you want to descramble protected channels, you will need a DVB-S2 card with CAM support (CAM = Conditional Access Module). In that you insert a CAM Module (which module depends on the encryption method used by your provider) and in that you will insert your subscription card. The CAM Interface is basically a PCMCIA slot, the CAM Modules are decryption PCMCIA modules with a smart card reader and your card is a smart card (thats what I know about it, I have no pay-tv/CAM).For the transponders:With a Multytenne you target several satellites all at once (e.g. Astra 19,2 ° E and Astra 27 something). For each sat you have a LNB ("antenna") in your dish. They are connected to something called a multi-switch. That is the one that is connected to your DVB-S2 card. Each sattelite sends out signals in many frequencies, in a high and a low band and in horizontal or vertical polarization. So your card tells the switch please go to High Band Horizontal polarization on sat #1 and it delivers all frequencies in that band (a single cable can not hold all signals that are transmitted at the same time, bandwith issue). So now your multiswitch (in your multytenne) picks a fourth of the signals of one of the satellites and sends them down the cable.Now your DVB-S2 card tunes to a frequency within that bundle of signals. Within this signal - called a transponder - there can be several TV programs (or radia stations, or internet data transfers, secret military protocols, whatever). So now that your DVB-S2 card is tuned to this frequency you can use all data within this transponder, so you can use all TV channels available within the transponder.If you want to use more than one transponder at the same time, you will not only need 2 cards (or a dual tuner card), but you will also need the proper dish / multiswitch. There is a multytenne dual (technisat), which you can use with 2 receivers / DVB-S2 tuner cards. So if you want to upgrade later, you have to have the right dish.There are several ways that blue-ray is supported, one of them is the solution you proposed.Another thing: CAM or CI support is the right name for descrambling channels. CI stands for common interface. So you put a smart card into a CAM which you put into a CI (easy, ey?)A last thing: morpheus_xx has developed support for the DigitalDevices DVB-S2 ( a dual tuner card with CAM / CI support). Have a look here <a href="https://forum.team-mediaportal.com/general-development-no-feature-request-here-48/digitaldevices-dual-dvb-s2-testing-cam-diseqc-82416/" target="_blank">https://forum.team-mediaportal.com/general-development-no-feature-request-here-48/digitaldevices-dual-dvb-s2-testing-cam-diseqc-82416/</a>A final word: You don't need a hw mpeg 2 encoder. You need a common interface (which the floppy dtv seems to have).</blockquote>
