On Demand Freezing Up

I've had my share of problems with Cox On Demand like everyone else, but I didn't see any recent posts about my newest issue.  While I try to go through the On Demand menus, it will get stuck on one tab, sometimes for as many as 3 or 4 minutes, but usually between 30 seconds and a couple minutes, and eventually "catch up" and whatever tab I was on will populate, or it will suddenly go through all my frantic arrow movements I pushed at once.  Sometimes it will just black out the screen for a few seconds and go to the general Cox menu, as if I had pressed the menu button.  I power cycled it twice, once unplugging it for about 20-30 seconds, and later once for about 5-8 minutes, and neither of these instances fixed a thing.

Unfortunately I'm kinda used to the bugs, so I just expect them to suddenly be fixed later, but when I'm putting on a movie for my 5 year olds or trying to put something on for company, it's just dumb...  Most haven't learned the patience with the product that I've ended up with...
