Hi there, Very long time TiVo owners here (since Series 1 on the "Cox Beta Test"). We currently have a Roamio six tuner downstairs and a Bolt upstairs. I've been dealing with some channels that absolutely refuse to tune on the Roamio, but were fine on the Bolt. However, now I've lost Science Channel and others on both of them. The previous Cox tech who came out last year replaced the box and said "Well, Cox only supports four streams per CableCard" as an excuse for not being able to tune six channels at the same time, but naturally blamed TiVo for the issues with tuning. I don't remember it being a problem before we moved two years ago. The SDV boxes were all kept with their matched TiVo when we moved. However, I think this last guy removed the "identifier" inline filter when he checked them since he claimed they weren't needed. We did start using MoCA as a backbone between upstairs and downstairs (and to the Mini) via two Motorola boxes since this house is not wired with Ethernet, but I don't see how that would affect anything. The TiVos are plugged into either my upstairs switch or a switch connected directly to a MoCA adaptor. So, what's the course of action to take with them now? I don't know if they're still rolling techs during COVID-19 or not. New SDV boxes? Thanks!
