Thanks for the info Norman. My X2 works fine if I only use it with one dish. The problem arises if I have the vbox and the HH motor in series on the same line. When I surf and go back and forth from C-Band to Ku-Band, the audio and video starts breaking up or the X2 just goes dark (no audio, no video). Cycling power cures the problem until I surf back and forth several times then I have to cycle power again ... very annoying to say the least. Are you using the X5 with a single dish?
