Thanks to both of you for your advice on this. I've got the box running on Hyperion V4 USB and it is running ok, but I'm having a bit of an issue that I hope you can give me a pointer or two about. Most, if not all, of my sly channels are freezing occasionally. I *think* it's ok and doesn't freeze when watching a Freesat channel like BBC 1, but on Sly 1 it keeps freezing.
I don't know whether it's caused by the box being slow or some problem with my Oscam settings... Do you have any pointers which may help? I'm not really sure that I'm using correct Oscam settings, but it is connected. Is Oscam an either 'working' or 'not working' kind of protocol? Or could dodgy settings make it work intermittently?
