I have a Samsung DSR 9500 VIA CI and a genuine Viaccess card from SRG, I have always this problem, after a while my card stops working (black screen), so I need to turn off the receiver and restar again. Perhaps I need to upgrade the firmware. My question is how do I upgrade my receiver's firmware. Where can I download the files? Does my receiver support Viaccess version 2.6 and version 3.0? Thanks.
