This means the new channels are in H.264, and was the same issue that other providers (Comcast was among the first as I recall) notified their customers of when they made such a change. This typically also means if you have an older STB (DCT/DCH?) you will need to upgrade the box (although maybe they have already pushed that part separately).The letter also states "NOTE: If you are using TiVo device series 1, 2, or 3, you will need to contact TiVo to upgrade to the newest series to avoid any disruption to your service".
So this seems like a new twist.
Left hand and right hand. They don't talk often. It is not a new issue for many large operators who seem to communicate some things poorly, but it is embarrassing. I would also guess that these new channels are also being added to a larger regional area, so the letter was likely written for many that are not just your locale (again, lack of hand talking).No mention in this particular letter about dropping support for CableCards.
I would not read too much into a lack of clarity, but no one other than Charter knows the actual schedules for your particular area.I have a TiVo Premiere XL4, which is Series 4, so apparently I won't be affected by this change. But the possibly better news is that the letter seems to imply that perhaps CableCard support is no longer going away, at least for now?
Completely separately, some engineering focused folk who have looked at Charter's plans have raised an eyebrow about Charter not mentioning some of the real world issues that they will experience and will have to deal with, and how it will impact schedules (such as potentially having to go inside every residence in some locations to remove/replace drop amps, and replace splitters and/or add filters, along with all the plant work expected). Comcast did some early field trials of their mid-split deployments and reported the results at various cable tech conferences many years ago now and how those tests results in changes to plans (and pushing out the schedules by what turned out to be years, although some of that ended up due to other changes in the plan that became viable). High-split has all the mid-split issues, plus more, so the engineering focused people expect the roll-out to be more of a slog than Charter has publicly acknowledged, so that could work in favor of those who want to continue to use their TiVo for just a bit longer (although, as always, your location will vary).
