Hi Peter, without knowing exactly what the situation is in Belgium, I can only comment generally on what I know to be the case. In Australia, we have DVB-T format for digital broadcast, so I have 2 x DVB-T tuner cards in my MediaPortal machine. Each different broadcaster has its own MUX (group of channels) which it broadcasts (eg., we have channels called "2", "7", "9", "10", etc.). Within MediaPortal, it's possible WITH ONE CARD to watch multiple channels from the same MUX, but not multiple channels from different MUXes. So, for example, let's say channel "7" has 4 different digital channels on its MUX, and channel "10" has 3 different channels on its MUX - with ONE TUNER CARD I could watch/record all of channel 7's digital channels OR all of 10's digital channels, but I can't watch/record some "7" channels and some "10" channels.

If I want to watch/record some "7" channels and some "10" channels, I need TWO tuner cards to do this. Similarly, if I wanted to watch/record a combination of "7", "9" and "10" channels, I'd need THREE tuner cards.

As I say, this is the situation for me, in Australia, with free-to-air digital TV. I don't know how it differs with satelite or with subscription/pay TV - this could be different.

From my understanding, though, all of the digital broadcast formats work in essentially the same way, so I think that if you wanted some flexibility in being able to watch and record multiple channels simultaneously, you're going to need at least 2 tuners (maybe more, if you've got lots of channels to choose from).

Cheers,
Craig

p.s. if you're interested, I started a thread/poll last year (find it here) asking people about how many tuners they were using. You'll note that the majority are around 2, 3 and 4, with a handful having 5 or more!
