I have been using Flash video MX pro to upload a videos with player skins for the past few years. I have not experience any problems when viewing them in the 32 bit format. However I recently upgraded my system to 64 bit IE 9 and unfortunately they do not run in that format but still do in 32 bit. Their representative told me that their software is not comparable with a 64 bit systems and that they are not at the present time planning on making it be.
Could some please post a link to a site that would provide me with the ability to upload videos with player skins that will run in both 32 and 64 bit formats. Going to The Imagineer's Chronicles and viewing it in both 32 and 64 bit formats will help you to understnad the problem.
