I don't know of an appropriate place to post this question but... I've been having trouble with my HR20-700 lately (the past few months). I've got terrible pixaliating (sp?) on this receiver on many MPEG-4 channels while my HR20-100 have been flawless. They're connected to the same multiswitch and same dish. This has been occuring even before I installed the multi-switch (WB16? Not sure which but it is the RIGHT multi-switch that I had inquired on before on here). Does any of you think it is "possible" that it is the coax cable that I might need to replace? Is it the BBC? I'd like to know before I go down into the basement and monkey around with the cables.
