Hello and good morning

I have a problem with my aljazeera sports card, I bought the card on last March and every thing runs well in my DM500,
until this month when the card stops to decripts the channels. I speak with the card vendor and he tells me "only works
with a viaccess receiver or cam" and I can prove that because I have a Samsung 9500 VIA CI, and the card runs well.

But I know it is possible to put a DM500 and aljazeera card runs and decript the channels, so I need help in order to know
how I can do that? What emu I need and it's configuration.

Thank you
