I'm on TWC in Southern California. Today, I'm seeing something new to me on many, but not all, SDV channels. The picture is coming out "scrambled". In other words there is a picture there that you can barely make out, but it has very high levels of digital artifacts. There is no TiVo error message and also no audio. I don't think it's the tuning adapter itself, because some SDV channels do come in just fine. I called the TWC cablecard number, and the very polite young lady there went through the TA diagnostic screen with me and sent a reset to the device from her end, all to no effect. She suggested swapping out the TA. Has anyone else seen this before? Any suggestions?
