Hi Peter
King of Sat might be useful as a resource. It tells you which channels are on each transponder. The 19.2e link is -->here<--. As Vasillich and Craig say, you need one tuner per *frequency* that you want to receive simultaneously. Also keep in mind that satellite dishes must be powered - this means you can only receive one "band" from a single LNB at a time. "Band" example: high band (above 11700 MHz) vertical transponders. In Europe you have four main bands:
1. low horizontal
2. high horizontal
3. low vertical
4. low horizontal
This is why people have Quad output LNBs - so that they can feed all channels into their satellite switches.

Hi mm,
How do these bands relate to channels/satellites?
We have 3 providers in Belgium, Telesat seems to mainly serve french part, Mobistar only sells triple play and TV Vlaanderen is what I had in mind since they have the majority of stations that we know in the flemish part.
From what I have found yet, they 'give access' (don't know if this is the right terminology here) to Astra 1 en 3 and from Satellite Finder / Dish Pointing Calculator with Google Maps | DishPointer.com I got this as being the most popular for Belgium:
1. 19.2E ASTRA 1H | 1KR | 1L | 1M | 1N | 2C
2. 13E HOT BIRD 6 | HOT BIRD 8 | HOT BIRD 9
3. 23.5E ASTRA 3A | ASTRA 3B
4. 5W ATLANTIC BIRD 3
5. 28.2E ASTRA 2A | ASTRA 2B | ASTRA 2D
Is that '1H' a responder?
The fact that Astra 1 & 3 are the ones I'm looking at and they are not completely in the same direction, does that have anything to do with the need for - in this case - 2 LNB's?
Apart from the number of LNB's and tuners, is there anything else I need then: dish, mounting arm for LNB's, cable and of course subscription? (to have a better understanding)
Is it correct that for watching 1 station and recording another at the same time, if it's not from the same... ?transponder?, I need at least 2 tuners?
How is a subscription linked to a system?
You see, lots of questions.
Thanks for this link, am trying to decipher it.
Is that *frequency* a range of channels and if so, is that what can be found on your link?
What do you mean by '... dishes must be powered'? That it needs a motor to be able to move?

Hi Peter2,
zou need one LNB per satellite group (or satellite ray). In your case : 1 LNB per satellite direction, e.g. 1 LNB for 19.2E, 1 LNB for 13E, etc. I have Astra 19.2E and Hotbird 13E, total channel number - around 2300, though a lot of channels are either on foreign language or encrypted. I am watching about 30 FTA (Free TO Air - i.e. doesn't cost anything) channels. So you should look to the link mm gave you (another source is LyngSat Astra 1H/1KR/1L/1M/2C at 19.2°E - LyngSat Hot Bird 6/8/9 at 13.0°E - LyngSat ), clear what channels do you want to receive, and then decide if you need any subscription (for paid, scrambled channels) or not.
If you decide to have only 2 satellites - then there are so called LNB Monoblocks with built-in switch, so you can have 1 or 2 or 4 cables that are able to receive any frequency on any LNB (e.g. http://www.amazon.de/Inverto-Pro-6°...sr_1_sc_3?ie=UTF8&qid=1325781621&sr=8-3-spell) , but it fixed for 2 satellites (e.g. 6 degree offset for receiving 13E and 13+6~19.2E). Advantage - you don't need to have extra power cables to HF switch.
If you decide to have more than 2 satellites - then you need to switch between LNBs, so you need external HF switch (multiswitch). Advantage - you can place your LNBs at any offset to receive satellites that are available in your region. Disadvantage - namy cables plus extra power cable for multiswitch (normally it is placed in th near from LNBs).

yes, this is correct.

Hi,
Yes, for Belgian htpc users is tv vlaanderen the only way to go.
For Astra 1 and 3, you need 2 LNB's or a duo LNB DUO LNB Twin | TV Vlaanderen Webshop
A 60 (65) cm Triax dish should be ok : Schotel Standaard | TV Vlaanderen Webshop
Then you need a smartcard and CI module CI module met smartcard | TV Vlaanderen Webshop
You can buy these parts by any tv vlaanderen/sat dealer.
Then you need a tv card with CI support Supported TV Cards - MediaPortal Wiki.
I shouldn't pick terratec or twinhan, I've had a bad experience with them.
If you want 2 tuners, you should better buy a dual tuner (they can share 1 smartcard over 2 tuners).
Each tuner needs its own cable to the LNB, so you need an duo LNB twin (2 connectors).
Channels with the same frequency are on the same transonder/mux.
http://www.tv-vlaanderen.be/uploadedFiles/Prospect/Klantenservice/Downloads/Zenderlijst_TV_VLAANDEREN.pdf
I don't use a CI module, because I share my smartcard over 4 tuners with the M.... plugin.
And I don't use mp tv server, I use 4TR argus as tv server.
It's possible that some CI modules don't work with some tuners,
I think there is some thread about it here on the forum.

Hi Glenn!
Thanks for clarifying, it's starting to make more sense and it's specifically for the situation here in Belgium. I have been to a shop where they sell satellite equipment but they didn't know anything about using it with a HTPC.
Regarding LNB: except for maybe space, fastening, price difference and the fact that if 1 breaks, you have to replace all; are there big (dis)advantages for 1 duo LNB or 2 seperate ones?
Is the 'Monoblock QUAD' that Vasilich refers to simply a double DUO LNB or does/can it have more to it?
In that pdf file with all the stations there is that 'POS' which refers to the position of the satellite and on the same satellite there is as well H (guess horizontal polarisation) as V (vertical) and even different frequencies.
So how does this translate to LNB/tuner if for example I subscribe to 'Basic light' but also would like to have the BBC which seems to be on Astra 2 (28.2)
Vasilich confirmed that I need 2 tuners to be able to watch and record simultaneously in every situation (that was for Astra 1 & 3).
2 tuners, even on 1 card - which seems more logic to go for - only have 2 cables and to be able to watch 3 different satellites (Astra 1, 2 & 3) do I need 3 LNB's, for example 1 DUO and 1 'single'?
Is there any specific advantage to 4TR regarding satellite?

A duo LNB is cheaper than 2 single LNB's + disecq switch (disecq switch is build into the duo LNB).
A duo LNB = monoblock LNB, quad stand for the number of outputs (4 outputs, 4 tuners).
So duo LNB single (1 output), duo LNB twin (2 outputs),....
If you want 3 satellites (for BBC), you have to use seperate LNB's and disecq switches.
BBC is FTA, so you can watch it without subscribtion.
And about the cam, the original tv vlaanderen/canaal digitaal cam can only decode 1 channel,

I'm using 4TR (argus) because it's much more reliable, I had many tv service crashes in the past.
