    I have a Comcast cablecard and i am missing some channels and Pixellating on others. I called tivo tech support and they had me run dvr diagnostics. One of the settings they were shocked at was the "RS corrected" which was over 9 million and my signal strength was about 36. The tech insisted i immediately remove the coax line because he said that my tuner will fry with settings like those and i need comcast to come out to fix this. He said if the unit gets fried, then all i will see is the tivo welcome screen and if that happened, the unit is dead.

    I would rather watch at least some of the channels i get until comcast shows up. Can this happen? I am a tech novice, but why would tivo software permit a poor signal level to affect the hardware of the unit?

    I have only had my Premiere a month. The cablecard install went fine, and this issue only popped up today.

    That tech must be clueless. If the cable signal level was extremely high, it's conceivable that it could fry something, but I can't imagine how anyone could design a circuit so poorly that a low signal level would damage it. And the software shouldn't have anything to do with it. Then again, I'm OTA only, so I don't know much about cablecards. If anybody could figure out a way to screw something up, it would be a cable company. But it sounds like Comcast did something to drop your signal level, and they just need to fix it.

    A signal level of 36 is extremely low but you will never hurt you TiVo by leaving it connected. That would explain your pixelation problem. Once Comcast fixes your problem check the signal level again and it should be at least 90 for a reliable stable picture.

    From what he explained to me, the extremely high RS value meant that my tuner was being overloaded with trying to correct the errors in the signal, and thiat is what could damage it. Does that make sense?

    No. The error correction (or lack of) is done by software using checksum correction bits. This would never hurt a fly, err... tuner. Just mean it's counting and trying to do its job.

    Out of curiosity how many splitters are on the line? Not just near the tivo but outside, in the garage our near the tivo. My mother one time had 4 splitters in the house and one outside.
