I am afraid there is nothing you can do unless you invest in a good cam.
Last official Echostar s/w release was vers. 1100 and that was, I think nearly a couple of years ago.
There were some models of the 2200(without viaccess embedded) that had a matrix cam fitted in place of the viaccess embedded. This was not an official version but an aftermarket alteration by some dealers to compete with recievers with embedded emulators.
