Connection setup for a STB and HDD recorder

[garyasta]

I have just purchased a second hand Pioneer DVR-520H-S Recorder. I normally receive TV via a satellite STB which is connected to a Samsung LCD TV. Input from the dish is via cable to the STB and then Scart cables to the TV.

There is another Scart output on the STB that indicates VCR connectibility (the recorder could connect here I presume). The recorder could then be connected to the TV.

In some diagrams I've seen, there is also a coax (aerial) cable running from the STB to the recorder. Is this necessary?

I understand that the satellite receives digital signals and the STB converts to analogue and that the recorder with it's in-built tuner would not be able to process direct from the satellite.

If I wish to record one channel (receiving via the STB and recording on the Pioneer) and viewing another channel (viewing via the STB to TV), What should be the connection setup?

Anyone any ideas (or diagrams would be best)?

In my experience, STBs that are not also DVRs can only tune one channel at a time, and all the video outlets provide the same channel. If that is true, without a second satelite receiver you will be limited to watching and recording the same thing.
