Can anyone provide the straight scoop as to whether ALL the Premium Networks, e.g. HBO, MAX, SHO, Startz. StzEnc, Epix, TMC, are now in HD as displayed when I view my Channel Guide using the Spectrum Website or via the iOS TV app? According to a rep at my one any only local store in Hilton Head SC, the answer is YES. According to the tech I got when I contacted Spectrum, I was told a bit of jibberish about tools they have to check things and that some are still SD only as they have always been going back to when we were TWC. I am not sure if the issue centers on whether one was previously a TWC customer before the merger with Spectrum, or whether I started my service with Spectrum. But considering I pay a lot of $$ for the Premiums, independent of the cable package I have, you should get whatever signal level they provide to any subscriber. But what do I know - I just pay the bills.
I am in a former TWC area, now on a Spectrum plan, and a couple of the duplicate premium channels are in SD. I'm not in front of my tv or on my home network to check on my phone, but I'm pretty sure I have a main HBO channel in HD and one in SD. Same with Showtime.
