Well I never got success with tuner 2, so now I am back to tuner 1.
Gonna go and buy a new cable, so I can test it directly from the head, to the Vu+
Without the other parts!
Would it be an idea, to have 1 head, directly to one reciver, and the other head, directly to the other reciver?
EG have 0,8 on one, and 4,8 on the other?
Both Tuner should work properly.
Tuner1 and 2 are identical.
BCM7335 DVB-s2 NIM (Internal)(dvb-S2)
Only difference is tuner configuration made by user(YOU).
You should be able to configure both, to receive same dish setup by moving the cable from one to the other tuner or
Use Tuner1 for 0.8Sat and Tuner2 For 4.8 Sat.
If I understood you correctly Your setup is DISH/2XSingle LNB/2-Port DiSEqC/Sigle Cable to Receiver .
Usually DiSEqC switch is the problem, due to compatibility issues or wrong receiver configuration.
Is your DiSEqC tone burst or Volt Regulated ? This is important setup issue.
To make sure your VU+ DUO isn't faulty, follow a911 and angelofsky1980 instructions,
Connect cable directly from Single LNB to Receiver Tuner.
Both VU+ Tuners MUST be able to receive same Sat Services by moving the cable from Tuner1 to Tuner2.(With Proper Tuner Config.)
-Connect Cable to tuner 1 or 2
-Setup both Tuners Configuration (Save)
-Recheck Tuners Configuration
-Scan services or download setting from server(Green\Yellow\Download\Settings)
-reboot
To change tuner repeat from beginning.
Good Luck.
