Over the past few months I’ve run across a few of these video player/aggregator applications. A couple of the better ones I’ve found have been ONTV and Democracy. Both these players are more than just video players. They both present themselves as internet television and provide a nice directory of videos all viewable right inside the application.
My favorite of the two is the Democracy player. It has the best integration of directory downlo and video. It provides 300 channels of internet video to chose from. You can set it to download the top videos in several different categories to watch whenever you get to them. It also will subscribe to RSS feeds to download your favorite video podcasts. And to save bandwidth, it integrates with BitTorrent. I like to usually have it set to download a collection of videos so I’ve got several things to watch whenever I’ve got some down time with the laptop.
