Is that enough to cause signal corruption? I'm wondering if there isn't any some equipment problem out in the Comcast system.
Thanks for the reply
On the other hand, the signal might be too strong. People with TiVo HDs have needed to put attenuators between the TiVo and the wall to get the SNR down from 37/38 to 31/32. My TiVos report 100% signal strength, yet still get uncorrected errors. I don't have any attenuators, although I've tried added an extra splitter, which can also reduce the signal strength. That didn't get the SNR down to where I want it, and anyway, I plan on switching to FIOS (for other reasons) before trying to fix this. The cable co boxes seem to be "tougher" when it comes to signal strength, which is one reason why the techs will see readings within a good range that may mess up other devices.
