Hi Martin. Thanks for your reply.
Visual Composer is such a good plug-in for making lovely looking pages quickly I think it may become very popular.
For your information, I found that a workaround was to create the code for FV Flowplayer in the normal WordPress edit window and copy then delete this code. Then creating a text widget using Visual Composer’s edit window I can paste the code in there. This all seems to work okay.
I’ll keep testing. Thanks again.
