Can the player display the SWF otherwise? How did you get the SWF you are trying to embed? Some issues you may want to check: - SWF contains newer tags then the SDK can handle (DefineFont4 for example cannot be handled in SDK <3.2). - SWF contains shape tweens - some such tweens will cause the SDK parser to fail. - SWF is to big - SDK parser will fail on very big SWFs, maybe it's just a wrong error message, but that's very unlikely. - SWF contains embedded video - I never tried this, but, since SDK has no parser for embedding video this may be an issue. - SWF was generated by some third party tool, which may not done it very well.
