The Vudu set-top box (from Vudu, of course) usually goes for $299. Right now the price has been cut down to $99. You are required to pay an extra $50 in movie credits--but that is kinda the point.

The Vudu box is for renting high-def movies on demand. The titles reside on the unit's hard drive until time is up. Since October, the box has support for a new format of its own called HDX which is meant to make the downloaded films look and sound better. The films are still H.264 videos, but with better encoding. Films cost $.99 to $3.99 in standard def, $3.99 to $5.99 in HD/HDX, and TV shows are $1.99. Some movies are available for permanent purchase, but they're only going to be on the drive, you can't copy them elsewhere.
