This is not unheard of, and it usually occurs in two cases:
A) Your server does not return the proper file size in the header of the video file, or
B) The video file is encoded some way that the file size is not available in the header. If your other videos work without loading entirely, I can only assume it must be related to option B. Video players use the file size extracted from header to figure out when to start playing after buffering, but if the file size is not available, it may not play until entirely loaded.

You didn't do this already? As specified in previous post, you can manually create your own thumbnail file. For example
videoName.mp4, need a thumbnail
tn_videoName.jpg. Just replace any existing thumbnail with that name, with your own jpg.
