Thanks for the update, let me know what the tech says... I am having similar issue's with NBC, it's nothing major, but it does not come in as good as ABC or CBS.
And I have the same situation with FOX, especially during American Idol.. The lip sync seems to be very distorted while watching on the PJ.
Trevor, are you having these issue's?? I know that you are on the northern side of Nashville, whereas I am just south of town off Nolensville Rd(in between 24 and 65 near Brentwood).
