Certain videos do not load (Weather Channel for example). Displays "Error: No valid source could be found" Using Windows XP with latest Adobe Flash Player (24 NPAPI). Thanks.

An error like "No valid source could be found" is always about the HTML5 media player and not about the Shockwave Flash plugin.

Since you are on Windows XP you do not have native support for playing MP4 files with the HTML5 media player, hence this error message.

You can try if the solution listed here still works for you. http://www.msfn.org/board/topic/175591-enable-mp4-h264-aac-html5-video-in-firefox-on-windows-xp-without-flash/
