The datarates are all set in the DVB spec. The real issue is the version of Irdeto SofCel integrated into the STB. Off the top of my head you need >= ver 2.4 to support the epsilon card. <br />Problem with Irdeto is that not all STBs are made equally. Irdeto makes their money by charging STB manufactures a royalty on each STB that they produce. Some, mostly Chinese and Korean, vendors fail to pay this fee, in effect pirating the SoftCel. But their SoftCels are never tested (DVT) and are always very old, but they are marketed as Irdeto STBs......... Buyer beware.....
