The DSM-330 is basically a media extender device that does many of the same things as an Apple TV or Xbox 360. You connect the box to your television and your home network via Ethernet or WiFi (802.11g) and you can stream videos from your computer to your TV screen.
The unit can handle videos with resolutions of up to 720p and has an HDMI port. The included software lets you access music, movies, photos, and online media. And DivX is encouraging third parties to develop applications that will run on the box, so you could see new software from independent coders or from big names like Amazon or CinemaNow in the future (I'm not trying to start rumors here. I have no evidence that either company is working on software, I'm just saying it's possible).
