Hi, the market for DVB-S inbuild tuners simply is not there. Its seems in Europe, Middle East and Asia where DVB-S services are king that the preference is not for inbuilt tuners, maybe the wide variety of service providers within anyone market means that to have multi STBs is not uncommon.
Cost? Because they already have a digital terrestrial and an analogue tuner? Because DVB-S is only standard definition in NZ?
To put another tuner in, means they'd need to reduce the number of other inputs / outputs in order to keep the price the same... and some of the entry level TV's have next to no connectivity to begin with! Look at the new Panasonic's in the UK - both UHF and Satellite tuners, but fewer connections (missing VGA for 2011 interestingly enough - which is a pain in the butt if you've got an older HTPC).
We MAY get both options in NZ when analogue is turned off though...?
It'd be interesting to hear the manufacturers opinion though.
