Changing channel with Twinhan SAT CI-1034 (1 Viewer)

[Alenet]

Hi!! I installed the last mediaportal RC2 onto Windows Vista Ultimate. It works fine. Very good! Great! Only a problem: it is too slow to change channels (8-10 seconds). It seems that the BDA driver is to slow to ask to CAM the initialization, because mediaportal waits something. The problem is the same with free channel and scrambled channel, with cam inserted or without it. CAM module works perfectly on nokia mediamaster decoder. I see that windows media center changes channel immediatly because it doesn't use CI but only free-to-air program. How can I solve this problem?
