Sorry, don't understand. If they are not ACM/VCM (this is the way this modulation almost always appear) then what are they if the are decoded without a problem with a card that supports ACM/VCM modulation (as TBS 6925 does), but not with other (standard DVB-S2 CCM modulation) cards or standalone decoders? There are already some known cases of transmissions of tv channels with ACM/VCM modulation that are not receivable with standard receivers or cards. 12718,H,36512 in Atlantic Bird 1 is one of them (Multiple Input Stream transmission, with four transport streams), a second one is 11914,H,27500 on Astra 1G with some italian sport channels. In any case most of ACM/VCM transmissions are indeed data....
