Hello Behruz and welcome. I believe the skystar 2.8 is made by technotrend, they are very popular cards so it is probably a good choice with lots of support. If you have dvb-s2 signals in your country you might consider a technotrend s2-3200 model pci card, it will pick up the dvb-s as well as dvb-s2 signals. There is also the Dvbworld s2 models, I have both a pci and usb version and they are very nice devices.
