I see a horizontal distortion on many recordings (see attachment, just below the rating box). Is this a manifestation of the AC hum Brian mentioned? I only see this on recordings captured with my PVR-500, not on televisions viewing the signal directly.
I don't have a STB, but Time Warner did install a powered amplifier before I set up the PVR. The outlets in use are properly wired (polarity and ground).
