When creating the flash file, be sure to set your intended movie size. For example, your typical banner would be 468x60, so set that as your movie size in Flash.
Then when you insert (embed) the code, be sure to set the same parameters in your html. In the case of using XOOPS banner and flash, use the html option and paste your source in the field provided. It may look a little strange in your banner admin, but it will display properly on your XOOPS site where ever you have {xoops_banner}.
Hope this helps.
