I reinstalled my Flash CS3 and now for some reason I cant play mp4 file using the FLVPlayback component. I made sure I have the latest flash player at least I think I did. Anyway, I keep getting an error in the output box. Is there such a thing as not having the most up to date player in the flash environment? I could use some help with this one.

VideoError: 1005: Invalid xml: URL: “D:\DONS\_INTERNET\_PROJECTS\Webriver\videos\WF109H.mp4” No root node found; if url is for an flv it must have .flv extension and take no parameters
