I just tested the Traffic Player plugin and really liked it. It’s handy because you can get a sales/squeeze video up on your WordPress site without eating your bandwidth or having to set up hosting.
The video looks like it’s professionally hosted as you can configure it to be without the YouTube logo, playbar and title line which can make you look like a cheapskate and removing the links stops people leaving your site.
If you set it to autoplay you’ll also build viewcount back on YouTube which helps the video rank higher.
If you make videos for clients and they use WordPress they could invest in the plug-in and have some nice looking skins on their site without visitors realising they are hosting on YouTube.
One downside I just noticed is the YouTube logo still appears when I view the video on my iphone. But that’s not a deal breaker.
