Dave,
I went back and tested tuner 1 on my PVR-500. All the channels on my cable
system (2 to 84) looked fine to me. My previous note to Hans was for tuner 2.
Everything was fine there too.
Scott Alfter -- my note about horizontal lines on channel 45 was on tuner 2.
On tuner 1, everything looked fine to me.
