I am using AllVideos (4.1) to play mp4 videos on my Joomla 1.5 website (using Morph framework).  The videos play fine on all browsers except the Android mobile phone.  I can play the Joomlaworks demo videos perfectly on the Android, so it is not a browser issue.  I would appreciate any advice in how to get this working.
Thanks
Mary
PS  The Joomlaworks demo mp4 video does not play on my android either.
