auto start will just not work. I have read the threads on this but still cannot find the answer. This is what I am using:  {vimeo}420617|483|254|true{/vimeo}

Same thing for youtube, eg:  {youtube}6lbvSBNLLoo|483|254|true{/youtube}

But nothing. Videos show but no autoplay. In admin autoplay is set to 'yes'.

Is it tha youtube and some other providers' videos don't autoplay?

This is a completely new install of joomla 1.5.10 so I am at a loss what the problem is.

I just loaded the extention module: mod_simple_video_flash_player
and it works perfectly. Autostarts everytime from youtube (example).

So its definitely an Allvideos problem. From the number of posts here relating to autostart, surely someone has a working solution? Please can anyone help?
