Hi Trevor, What cable box was this? I have a GI/Motorola DCT2000. They don't actually digitize the analog signals, they just overlay the EPG on the analog picture. Unfortunately, these boxes are built very poorly, and there's lots of signal loss through them. I had one that would de-tune when it got hot. The effect was the picture would look almost like the old scrambled analog signals.

Unrelated related story, I got a digital cable box a while ago, and it also tunes analog stations but internally it digitizes them somehow and then can show them on TV with an overlay for program guide and information and such. When I first got it, I found the digitized version of the analog picture looked much worse than the real analog picture, so I would use the digital cable box to find the show I wanted to watch, then watch it on the analog station. Later, my signal got weak and I start to get a lot of dropouts and such, so the cable guy installed an amp, which solved my problems. It also made my signal stronger, and now, the cable-box digitized versions of the analog signals look more or less the same as watching them in analog. So... similar to what we all think is happening here, the weak analog signal looked fine but didn't digitize well when it was weak. Got really grainy and overly sharp. -- Trevor Boicey, P. Eng.
