We have found that NCIS and other programs that we record on Spokane CBS is often pixelated. The problem seems mostly with CBS, but also affects other networks from Spokane.

Our signal strength and S/N ratios are quite good for all channels when we are watching live TV, but I can't say about most channels since we record everything for later playback.

BTW, our recording of CW WPIX New York "Supernatural" went macroblocky and finally quit.
