So DVB-T card seeing DVB-C modulation is like me (and probably you) seeing Hebrew.. >From DVB wiki: These distribution systems differ mainly in the modulation schemes used, due to the different technical constraints: * DVB-S (SHF) uses QPSK; * DVB-C (VHF/UHF) uses QAM (64-QAM in general); * DVB-T (VHF/UHF) uses COFDM.
