S3 HD (652) OTA and analog cable (TWC) No digital cable, no cable cards, no TA I guess this thing really has 4 tuners, 2 in the module that sticks out the back where it says antenna, and 2 in the (appears to be indentical) module that sticks out the back where it says cable. I can get two different OTA channels at a time with a decent antenna, but when I try for analog cable, only what it calls tuner 1 can get it, tuner 0 gives me the "searching for signal" excuse screen/overlay. It shows frequency shifting, by about 12 kHz, I guess as it tries to lock in something, or else it jumps frequency by more than that and modulation cycles though analog, QAM256, and QAM64. I swapped in the power supply from my other "both cable tuners work fine" S3 HD, and it doesn't make any difference. Naturally the one with the problem is the lifetimed one. Anybody got any ideas what the problem is? I've tried an inline attenuator in the co-ax feed, and tried it straight off the main feed before the splitters, and zilch, so I'm tentatively ruling out too hot or not hot enough a signal. I can get tuner 1 to do that same "seeking" frequency and modulation dance if I disconnect the cable and try to tune a cable channel, so maybe that's a clue. If I ever issue any terrorist demands, it'll be to force TiVo to release schematics.
