I have a DM800 setup and I had issues with four HD Channels. It is known issue and the fix is an inline booster.Over the Xmas I installed an inline booster and these channels were perfect. The thing is with the inline booster as these channels are perfect also with the booster a number of channels are gone with no signal while others glitch with high BER rate. Without the booster all others are perfect. How is this so? Is my dish not alligned correctly? Any help appreciated
