Audio Sync Problem on G10R channels

[dadamus]

I finally got everything working.
Good signal strength(81%)+Quality(90%).
Picture looks great, but having trouble syncing audio for ALL CHENNELS.
Roughly .5 to 1 second ahead of picture. I turn LNBF little by little on both direction.(Changed direction when quality drops below 70%), but audio refuse to sync.
I'm using Fortec Star Universal 0.50 dB dual KU LNBF and DVB-786v3.
Is this receiver or LNBF problem?
TIA.

Make sure your quality is high on most transponders, not only one. Also, LNBF must be tilted the right way or your signal will be weak.
