The image was perfect so I suspect that the CAM itself can handle it unless the TV did HW PID filtering before sending the stream to the CAM, as you point out below... Is that to be expected? > 2.

Do you have a recommendation for such a card? Would it be possible to do the filtering in software somehow? > 3.may be some fixes can be made on TS output from demod.

Unfortunately, I don't have the necessary equipment/knowledge to do this. :( I'd assume the DVB provider could give me the TS clock? But then I'm at bit at a loss with "change TS timings/forms in demod". What exactly are you referring to by "demod".
