Viacess is another encryption system, used by some providers transmitting from 5 degrees east (Viasat nordic and Viasat balticum) and from 13 degres east (viasat europe and a bouquet of french providers).
A lot of Viacess hexfiles are available, but there are still problems with a few recievers with a Viacess embedded. This can be solved by using a Viacess CAM which cost about GBP 80.
You will find hexfiles for Viacess in #sathelpers chat. Did you visit the chat today?? Otherwise you can still make it ;-)
