CCcam don't run on chinese Skybox receivers.
SkyBox (and Openbox) receivers can connect to CCcam servers but don't run CCcam. It's a big difference.
The chinese recompiled the MGcamd to run on SkyBox/OpenBox and renamed the file cccam.list to CCcam.cfg. In this way you can use C lines to connect to a CCcam server. The lack of firmware optimization make the connection very unstable and unreliable. Also CCcam.prio doesn't work either. You can't do nothing to improve this only to wait for a new and better firmware. Since the production of Skybox receivers is stopped (they switched to X-series now) i don't think they will invest time in new firmware for F-series receivers.
Hope this information doesn't come as big disappointment to you but this is the result of false advertisement by SkyBox/OpenBox sellers.
