Since these channels were launched, I have consistently had audio sync (or maybe it is video sync) problems. FOODHD is quite bad, while HGTVHD is a bit better (closer sync) -- I understand that the two channels are owned by the same company. Is this a known problem or could it be my HR20? I do not have any audio sync problem with my other channels (other than random occasions, unlike FOOD and HGTV, which is always the case). I have tried doing pause, rewind, FF, stop, channel up/down, reset buttons, etc. (no help).
