Sendvid Might be a Good Alternative to YouTube and Vimeo for Video Hosting
I've heard that some companies host their videos on Vimeo rather than YouTube because they feel that YouTube's interface isn't a good fit with their branding. Unfortunately, Vimeo has a tendency to disconnect and be unstable.
Sendvid is a simple, free video host that I've heard of. I haven't used it yet, but I have used their other service Imgbox (an image hosting website) which I've found reliable and useful.
