Theory: The Moteck may be designed this way. If it was faulty it would not move the dish etc. Point to note here aswell. There is mention of this in the troubleshooting in its manual saying its because the LNB is powered.
My primesat Vbox remains powered at all times the tuner is active.
When my ultimo is in standby the primesat also goes to standby
When i select an IPTV channel my tuner goes off, and the primesat again goes to standby
The primesat also goes to standby if i use other tuners.
As far as wiring goes, there can be one way of connecting up the Vbox so doubt it is anything to do with that.
It is your tuner set up that bugs me,..
I dont use the FBC tuners (because they cant blind scan) i have an old normal type (non FBC) Twin tuner in the 3rd slot that comes up as tuner I and J
The vbox with the 1.2m dish are on tuner I and another 80cm usuals dish in on tuner J.
When i bother i add other fixed dished to the FBC tuners.
Is i get a chance later i will try and mess about with the FBC tuners.
if i was using my current non FBC twin tuner - with one dish and twin LNB like you have.....
i would have the tuner setup like this:
