Thanks for your reply!
I appreciate your looking into this. I assure you, however, I have double and triple-checked my accounts, passwords and anything else I can think of. I have emptied caches, updated browsers, turned off (and on) all plugins and verified that pop-ups are not blocked, that cookies are enabled and tried with both Macs and PCs.
There could possibly be some quirk on my system but I'm at a loss to figure out why it works seamlessly with ESPN and other streaming content that use the same (or similar) protocols and I'm reasonably sure there's a glitch somewhere between Charter and TCM.
For example, I was able to watch a movie by signing into Charter's site and linking to the TCM live streaming content from there. But only the live content worked. The button that linked to Watch Now movies that are not live returned an error saying no content was found.
Oddly enough, I had a TCM live streaming movie running in one tab from Charter's web site (indicating I am clearly "authorized" to watch TCM content), while in another tab containing the TCM page for the same movie I had the now-familiar error dialog stating I was not authorized. I just re-created this scenario and have attached a screen shot.
The number shown in the error message is Charter's main number. Going there and finding tech support led to a pleasant conversation with a sympathetic rep who supposed there was some problem with TCM's site because everything on Charter's end is working correctly.
I am sympathetic with the problem of tracking down such an obscure issue but I can only hope your people not take a pass without looking into this. They can contact me directly if I can help.
Perhaps if somebody from Turner got on the phone with somebody from Charter, a solution could be found. I'm not hopeful about this, though, because I'm sure that both of their systems are working beautifully, which makes it look like nothing is wrong.
But take a look at the attached screenshot. There is Robert Osborn, right there before my very eyes. I am clearly "authorized" to watch TCM content and my system is clearly able to view it without issue. The "problem" may indeed be some obscure setting or other oddity on my system but it seems to me that it would be of interest to your (or their) coders because I've exhausted every possible remedy I can think of. It appears that there's a issue in the handshake between Turner and Charter that I can't do anything about and I'm guessing that some smart person would just love to be the one to figure it out.
Thanks again for your attention to this.
