I am having no success playing a short FLV through a SWF on my hosted web site. The video plays without problem on my local PC. This problem only occurs with SWF and HTML created with Flash CS5. With Flash CS3 the problem does not occur. The only difference I see between CS5 and CS3 files is this: There is a file called AC_RunActiveContent.js created with the SWF and HTML through CS3. But that file does not exist with the SWF and HTML created through CS5. Since the video plays on my local PC, I assume that AC_RunActiveContent.js is not required for newest version of Flash player. My web host provider assures me that MIME settings are correct and Window 2005 is the operating system. I am at my wits end trying to determine the cause and fix for this problem. Please give me some advice for resolution. Thank you.
