Advertisements I'm wondering, has anyone else experienced a similar problem: I have one HD channel (733 NBC on Cox Cable Las Vegas) that has intermittent audio outages. Approximately every 2 or 3 minutes, the audio drops out for a few seconds (no pixilation as I've seen in other posts) I've call tech support. They flashed the Cable Cards to the latest firmware, but nothing changed. The tech support guy said he couldn't think of anything else to do except replace the Cable Cards. But since it's happening on both tuners, I can't believe both Cable Cards have the same defect. Does anyone have a theory as the whether it is a cable problem or a TiVo problem?
