The OSD can record from any analog video source, from a TiVo to a satellite box to a DVD player to a games console. It records to any removable media you plug into it, such as a USB thumb-drive or a hard-drive -- so you can record your favorite DVDs, your best video-games, or your TV shows straight to drive. Needless to say, it'll play back from all this media as well.
The OSD is networkable, and can schedule programming in advance like a TiVo. It can play back all the standard download formats, including Xvid and Divx.
Best of all, the OSD is open: anyone can hack its firmware and add features to it.
Now this is a DVR that I just might buy.
