My Hr22 HD box is very sluggish when it comes to navigating through my now playing list. There's a second and a half delay and to go down five spaces, it takes either five keystrokes, or holding down the key for three seconds and then it skips by it. My Directv TIVO was very fast and responsive. This thing is driving my crazy. It has such lag- especially when deleting. Is this normal? Can't wait til the new Tivo comes out.
