I get all channels from IRCI 5400Z recevier except for the pay channel which I will receive only after inserting viaccess card. When I insert the card into the receiver, I get a message that it is an invalid card. Also I should be getting the channel video continuously even without inserting the card. However now I get the video on and off, not continuous. Please note that this problem is only with this channel. All other channels are functioning normally.
