Searchforvideo is a relatively new web-wide video search site you might want to check out, while Guba and VideoEgg are two other video sites that will be of interest to those who want to share video or see what others have contributed. More details below:
Searchforvideo allows you to keyword search for video content from across the web. You can subscribe to RSS feeds of your searches, so you can be updated when new content matching your query is found. You can also browse subjects by topic, as listed above the search box on the home page. Got your own video content you want included? Submit your feed here.
Guba, which has allowed you to locate video posted to Usenet, has now opened an uploading service. Similar to YouTube or Google Video, you can upload your own content, then others can search through what's been contributed. Uploaded video is converted to Flash, iPod and PSP formats. While part of Guba is a subscription-based service, searching and viewing uploaded content is supposed to be free.
VideoEgg is similar to Guba, in that you can upload and share video. SiliconBeat notes that the service is now allowing publishers to upload content in a variety of formats, where it can be hosted and then played back on their own sites. Unfortunately, there's no way to search through VideoEgg-hosted content at the moment, that I can see.
Postscript: Actually, Searchforvideo's been out since October, but the RSS feeds are apparently a new feature.
