Advertisements There wasn't on my TWC system (Southwest Ohio). This info is of no interest to 99+% of their subscribers so the tech support people don't usually have it handy. I assume most subscribers get reliable lineup info directly from their TWC set-top box or DVR. When my cable cards and TA were installed last July the installers couild not even give me a list of the channels I should receive. I keep asking for channel lineup brochures and they keep sending them, but they are never up to date. They have a channel lineup webpage but it is so user unfriendly that it's practically useless (and doesn't distinguish SDV channels at all, of course). I once made a tech support person read me the list of SDV channels over the phone, but later determined it was inaccurate and incomplete. There is a way you can tell if a tuned channel is SDV, see **this post**.. This is tedious and of course requires you to be able to tune the channel -- not helpful if you're wondering if you're failing to tune SDV channels that you should receive.
