I assume what he means is, encase the link he provided (to the .swf file) in the [FLASH][/FLASH] tags.
Basically, you follow my tutorial on
how to add YouTube Videos for Version 8, but replace the Youtube link for the Vuvox one. This can be used for any flash video that is simply a link and doesnt need other parameters with it (some flash videos have extra fields of information to pass information to the flash file.)
Note: As well as the link you need to enter the height/width variables to the flash tag, see my tutorial above for more info.
