Advertisements As espo mentioned, every single S3 owner in Howard County, MD seems to have this problem. I don't know if every CableCARD device does it, or just the S3, since Comcast has refused my every request to try my CableCARDs (or any CableCARDs) on a different device. I understand about your returning the TiVo (although I myself am stubborn and actually bought another S3 without having resolved this problem). I wish TiVo could take a more active role in helping resolve these problems, even if they think the problem is with the cable company. I've called them, but they basically just said the problem was with Comcast and I should talk to them. It doesn't matter whose fault the problem is - if it can't be resolved, most people won't have any choice but to keep Comcast and drop TiVo. If TiVo could tell us what's wrong in cases like this where at least a whole county is affected, we'd have a better chance at getting Comcast to fix it.
