yes. Maybe you need to adjust some hardcoded parameters in the example 
codelets like the LOF which might be different for LNBs bought in the 
US, maybe you also need to check whether your equipments supports teh 
DiSEqC for LNB and switch control. If not you can still use the 
loop-through of an existing receiver to control your LNB and switch.

For satellites that transmit plain MPEG2 in a DVB compliant modulation 
you should have no problems at all. Beside them you have the DirectTV 
satellites in the american sky. DirectTV satellites are using DSS as 
modulation scheme and shorter MPEG packets, the MT312 demodulator used 
on the older SkyStar2 cards can handle them, but nobody tried this yet 
and you probably need to modify some parts of the driver to get this 
working.

So it's easiest for now to use the DVB/MPEG2 compliant satellites only - 
when you find some time you can dig deeper into the code and try to get 
the DSS stuff working...
