Why isn my video showing on my WordPress blog?
I think you are using the wrong video blocks or settings. There are now many plugins or other features that can help you do this. Also read more about WordPress optimization here to see how to improve your site.
Version 2.0 of the popular WordPress blogging software has a bug that prevents cross-posted blip.tv videos from showing up properly. To fix this problem please upgrade WordPress to version 2.0.1. If you’re using the WordPress.com hosted blogging service we strongly recommend that you use our cross-posting feature rather than copy & paste HTML because of WordPress.com security software.
