I have a 2nd series Tivo with Time Warner Digital cable. My setup was working perfectly with my Tivo remote using IR cables on the cable box.
Up until a week or so ago, that is.
TWC, in its infinite non-wisdom is making a major lineup change here.

(Probably using us as guinea pigs for it as a matter of fact.) Apparently some moron thought grouping channels by type was something reeely helpful for their customers. :>p...
It might have been of some value if they hadn't proceeded to make an effing mess of this "great upgrade". I wish I knew who asked for this. It caused quite a bit of hicupping over several days to my service and screwed up my recording. Why do I think this is actually to help TWC with future pricing structures?

Okay, rant mode off. So once I got the brochure in the mail from TWC with the new number listings, I went thru and re-did my channel lineup in the settings with all the new numbers.
Most of the hicupping seems to have settled down except for this: since the changes, using my Tivo remote, I can't access any but the lowest Showtime channel. The old numbers were in the 400s and now are in the 600s. Mind you, I get the show information at the bottom for each of the Showtime channels but I can only get the channel to actually change if I use the TWC remote (most of the time). (And if I hit any number higher than extended basic, it takes me to that Showtime channel too.)
I called TWC who said they are being inundated with calls about the changes (HA). They showed me how to use the TWC remote to get the premium channels. But she said it was a Tivo problem and not their fault.
From responses to previous posts, do I have to contact Tivo about the new channel numbers? Why would I get one and not the others? The old lineup had no 600s. If I do need to let them know, can someone point me to the link or contact info?
I'm getting more phone connection failures since this started too. I don't know how, but could that be related to these changes as well?
Please try not to be too technical in response - I've been told I only know enough about these things to be dangerous.
Thanks for any help.
