Regular readers of Home Theater might know that I also write the “Top 100 DVDs of All Time” article each year, which means that I have at least 8.3-dozen discs at home. And those discs tend to pile up. But how else is a cinephile supposed to build an impressive video library? Kaleidescape is too rich for my blood, DVD jukeboxes are too difficult to manage, and downloading movies to my computer isn’t really a living-room experience. So there’s the Apple TV, which recently began high-def movie rentals, not purchases, from major studios directly to the box. The Xbox 360 also allows paid download-to-own TV shows, some in high def, although all movies are rental only. And then there’s VUDU. The VUDU box is essentially a movie machine, a library on a hard disk drive inside a box. It’s an entertainment portal that sits quietly next to the TV until called into action.
