No it will not, because modulation if different. 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.

Best regards, 
Jori
