Why am I losing 4 movie channels from my package?

What channels are available are subject to change at any time. There is no guaranteed price adjustment for it, nor is one obligated.

Also likely means HBO is not lowering the cost they require to be paid for their pack. As such DirecTV couldn't change it per that restriction.

Because HBO decided to downsize their number of channels in the offering.  DIRECTV cannot provide to you what HBO no longer provides to it.

Got it.    

"Bend over and accept it."  Thanks DirecTV.

You agreed to it per the TOS you signed when it was installed.

What channels are available can change at anytime. Unfortunately, it is expected per contractual obligations that DirecTV is not allowed by HBO to lower the price. So your "thanks" should go to HBO as well at the very least.

That being said, if HBO keeps their channel count reduced, which means less content provided simultaneously as opposed to a large variety of channels, that should be a point addressed when it is time for DirecTV to renegotiate the carriage agreement with HBO (or perhaps able to affect the next annual price adjustment if we are lucky).

If you cannot wait for that price adjustment or the next time those two negotiate, then just remove the pack. It is optional, so it is up to you to accept it or not.

Thanks DirecTV.

Thanks DirecTV HBO.

Fixed that for you.
