[QUOTE="HTPCSourcer, post: 1123655, member: 74879"] You need to be clear about a major difference between cable and SAT. The former has a bus-character, which means that you can draw one cable linearly from point to point and connect a TV anywhere in between. SAT requires a star-like connection: every receiver requires his [U]own[/U] cable, drawn to a central distribution point. WHy is this? Well, every receiver switches the LNB between horizontal and vertical polarization plus changes the switching frequency between 22 and 27 kHz --> this gives you four states per receiver. There cannot be different states at the same time one the same cable (well, except for Unicable installations, but that 's a different story,which requires additonal hardware), and that's the reason why a standard SAT installation has four cables. Now what do you mean by "network-based tv-tuner"? A MediaPortal TV-Server? If you want to watch TV with MePo clients only, all you would need is a MePo TV-Server PC, which houses the DVB-C cards. The dishes that you selected do only have Twin-LNB's - that means that for each channel you will be able to watch ONE channel and record ONE other channel only. If you had a Quad-LNB there would be no limitation (other than your PC tuner hardware limits). If your two Twin-LNBs will be connected to your MediaPortal server only, you will require two dual tuner DVB-C cards (or four single ones) to which you can directly connect the cables from the dishes. If, however, you would like to use the dish signals [B]in parallel[/B] to MediaPortal, you will aditionally need the above-mentioned multiswitch to further distribute the signals. Clear as mud?
