Wouldnt it be easier to buy one or two DVB-S or DVB-S2(for HD) tuners? That would give you massively better image quality(no digital->analog->digital conversion or recompression). Thats also the only way you will get HD working.
To use two DVB-S tuners this way you will need 2 smartcards or a smartcard splitter.
