As far as I know E2 requires a special patched bin with stream relay to clear icam.
I use PC so I don't need any special version of oscam or stream relay... In fact I don't even use oscam, I use ncam.
Sky UK (SD) and DE clear for me, but I haven't found any servers that clears IT yet.
Do you use windows or linux? If windows what is the configuration of ncam and what SW do you use to watch SKY DE.
