One of the absolute best things about the internet, for me, is that it lets users time shift content to match their schedules, rather than being dependent on a network timetable.
To that end, the one product I use more than any other is Miro.
Miro is an open source project that allows users to download videos from anywhere on the net as channels. Users can create channels from favorite searches on engines like YouTube, or they can subscribe to video podcasts who enable Miro. The technology behind Miro is quite impressive, combining torrents, open source video, and RSS feeds to put together a free, open, alternative to the tv.
