Hi Blackspreen
I noticed the error page shows “Powered by WP VideoTube” I would start off with disabling that plugin. If that doesn’t resolve the issue disable all plugins and switch to the default theme. From there, re-enable plugins one by one until you determine if this is a specific plugin or combination of plugins or issue with the theme.
Hope this helps!
Based on the source code your search page generates, I would first try disabling the VideoTube plugin. It looks like it’s failing to output a video correctly and giving you a garbled mess.
