Pixilating....again!

Whats with the constant pixilating!  It's been going on now off and on for a few days.  This is my third complaint over the last few days:  useless guide, black screen and now the pixilating.  These complaints, while minor, are frustrating and coupled with the $20 a month rate hike aren't conducive to customer retention believe me.  Your are suppose to be able to enjoy your TV viewing experience aren't you?

HELP...again.
