OnDemand

Hi, every time I try to access OnDemand from my bedroom box, it goes all the way to the "hit play" screen and once I do, it suddenly jumps to a blue screen as if I'd hit "input" and changed the TV channel. It's been doing this for about a week. I've tried unplugging my box and plugging it back in, but no luck. Super annoying. I want to watch Bravo! :-)
