Lena,
Thanks for your reply. I've tried everything and nothing seems to have helped. I went and got another receiver and it does the same thing. At least I know it's not my 1050.
The distortion is not sporadic. CNN, Fox News Channel, local stations etc. always have this distortion (voices seem most susceptible) while other channels never do.
I have a Hughes receiver with tivo. I don't know any settings that I can change that would maybe effect any of this. Perhaps you can elaborate.
