Does it cost anything extra to go over 6 receivers? I want to add a 7th? Just for fun I went to the online account to "activate" a new receiver ( even though I didn't have one) it says "Your account has six or more activated receivers. To activate additional receivers, please call 1-800-531-5000 for assistance."
It's the same price for each extra receiver/dvr, but it sounds like Directv is being proactive when the numbers start getting suspicious, or at least what they think is suspicious.
