I've been with TWC for about 6 years, with 2 TWC DVR Receivers and 3 Tivos with Cable Cards with about 3 TB of total HD space. TW said they were taking away my Price Lock Guarantee and not renewing it.
I decided to go with DTV and got a good deal. HR34, HR24, and a R22, with $198.00 up front, plus free installation. $29.00 discount for 1st 12 months and $10.00 for months 13-24, $10.00 Discount for 24 Months for auto-pay, AAA $10.00 discount for 20 months and free NFL Ticket.
So I'm getting Choice Extra, for $51.99/mo for first 12 months with discounts expiring after that. That's a really good deal considering TWC wanted to increase my bill from $87.00 to $107.00 and would not negotiate.
I've had all the services over the last 16 years playing the switch game, Dish, DTV, TWC and including 10' C-band/Ku-band satellite dish. The only way to really get a good deal consistently is to be ready to walk out on your current provider and be ready to switch to the best deal available at the time. I find it works well with cell phone companies, internet and phone service providers also. If DTV doesn't give me a reasonable deal in 24 months, I'll go shopping again.
