Help please, I purchased a YESS DVB-S2600U from 1 Day a little while ago. I can not get it to record CH 3, TV 3 plus 1, Prime if I am watching CH1 or CH2 at the same time. Also vice versa, if I am watching Ch 3 I can not record Ch1, Ch2 TVNZ 6 etc. They don't come up in my list of channels to record. Am I doing something wrong or is it to do with oppostion TV companies?? I would really appreciate feed back on this as it is driving me crazy. Thanks

DVB Signals are transmitted as a number of channels multiplexed together (called a 'mux') and broadcast from a single transponder. in the case of freeview DVB-S, there is one mux for TVNZ and another for TV3/Prime (and possibly some others)

I'm not familiar with that device, but most likely it has a single tuner. That means it can only tune into one mux at a time. It can potentially (depending on other limitations of the device) record all channels on that mux, but you'd need a device with at least two tuners to record channels off a different mux.

Thanks so much for that, I have checked the manual and it says its fully DBV-S/MPEG - 2 compliant - so I'm guessing it is as you have stated. Thanks again.

This is the wrong area in the forum to be posting this in, but regardless I'll give you an answer as I see it.

It looks like you've purchased a satellite receiver with a single tuner, rather than a dual or tri tuner setup.

Basically NZ satellite is broadcast by different providers on different 'muxes'. A mux is like a stream containing different tv channels. Currently:
TVNZ = 1, 2, 6, 7
TV Works = 3, 4, 3+1 hour
Kodia = Everthing else

are the main 3 muxs.

Your single tuner receiver can records channels on 1 mux only, meaning you can get all the channels on that one mux if you're recording but none of the channels on the other muxes. If you want to record channels on 2 muxes you'll need to get a satellite receiver with 2 tuners, and a 3 tuner card will pretty much record/watch any channel at the same time.

Most people stick with dual tuner receivers as they are generally enough unless you're doing a lot of recording/watching.

Hope that helps..

Thank you for that, guess I will have to start hunting for a satellite recorder with 2 tuners in the near future.

Elkano, unless something has changed, the NZ Satellite service only uses two muxes, meaning that a dual tuner card will give you access to all channels broadcast from the Satellite service. The HD terrestial service uses three muxes, but for Satellite its only two.

Thanks Mike, I wasn't aware there were different numbers of muxes on the satellite and terrestrial. Smile

Of course on satellite there is the issue of polarity too (meaning you need more LNB's depending on whether the mux is on a vertical/horizontal polarity). Luckily this is only an issue if you're trying to watch SBS channels currently as all the NZ ones are the same polarity.
