Problem with Dreambox 800 HD PVR

  • Greetings. Before some time, I bought a dreambox 800HD. Also use a Stab motor 120 cm. My problem is this: When I change the channel from one satellite to another motor moves and does not stop in the proper position but exceeds it. Occur two cases: first case-when I go from Top Chanel (16 WE) on RAI UNO (13 E) engine runs in the correct position, but when the pass immediately to the SFR (at the same satelit13 E, but with different frequency) to move the engine restarts and loses position 13 E. The second case - when I go from RAI UNO (13 E) to Tring, Tring (16 E), the engine finds the position but stops and turns back and continues to move, or continues to move by shifting the correct position.
    Thank you.
