So I asked... it could only be in Octagon.
Abertis (streamrealy) is simply full of freezes, streaming to the PC stops a while. If you use OBH in a Vu+, Abertis has no problem.
Transcoding seems to be ok... For the smartphone it is better to use Octagon, as H.265 solves the well known odec problems in Hispasat (Portugal providers).
Even now with PlutoTv is to forget... The box ends up blocking, you need to resort to telnet.
My connection is by 500/100 network cable.
It's not the box, just move to another firmware... I usually get in openSPA, and works well.
I've noticed a long time ago.
