General rule of thumb.
If your single tuner card has an output, then it wont loop through internaly.
Xtrend say the same in their blurb (manual).
Get an external F-jumper lead (out to in) and in settings for second tuner set same as tuner A
My box does NOT have any outputs, only lnb A IN and lnb B IN, and additionally it should do the "internal loopthru" as the salesman told me ?
I can not loop it externally as you proposed, this worked on my old box that had 2 physical tuner cards with both in and out but not on this Vu+
The receiver shows Tuner A and Tuner B in OpenPLi tuner setup so now I am pondering the settings in PLi for getting the internal loop to work, I have not tried with a static feed from the dish only with the USALS settings and maybe this is the culprit why it is not working? I need someone to confirm the internal loopthru works with motor setups also.
thanks tho!
