This has baffled me to know end. A few days ago my computer lost the ability to play any progressively downloaded .MP4 video through flash on the web. I have a whole site of videos that quit working for me. I can view videos encoded as .flv or .wmv on site like vimeo or youtube but if it is .mp4 extention the video just spins and never plays. I need to find a solution to this ASAP so if any one has any insight, I would be forever greatful! MP4s play fine locally on my machine or even through a direct link, just not through a progressive-dl flash player on the web.
I'm on a XP-64 machine with CS3 suites and quicktime installed.
Things I have tried.
-Uninstalling and reinstalling Flash
-Searching google for similar problems.
