After L7.50 downloaded (maybe 2 weeks ago) my sluggish, and sometimes incomplete guide issues went away. Today, I'm sorry to report, one of those came back. My 722k's EPG only extended until tomorrow (Sat) night and I had to download a fresh copy of it. The other problem (sluggish EPG response) has not come back to life, but in its place is a slight (barely noticeable) across-the-board delay - all functions. I can live with this, ... ... but it would be nice if Dish would permanently fix the Guide once and for all.
