I'm going to just take a moment to compliment TWCNYC - it's so rare that I have this opportunity.
I have a Tivo with cable card, and I'm lazy enough that I just put off doing anything about getting a TA. About a week ago, TW called me and arranged to have one installed for free.
Today, the service guy came by and installed the TA. He called first, then arrived on time. He was polite and seemed knowledgeable. He installed the device quickly and was on his way in about 15 minutes. When I gave him a tip, he acted genuinely surprised, paused for thought, and then accepted it.
All in all, it was a very good experience. Of course, all I know, right now, is that the TA works fine when there isn't any SDV. The proof will come in mid-July, if that's when they still plan to roll out SDV.
