how to add more options to my BBcodes?

[Lautaro]

Hello, im looking for a way to create a BBcode with multiple options.
My main idea is to create a Windows Media embed BBcode and let the users change the options:

{param} : it will be the link to the video file
{option} : (1st option) video width
{option} : (2nd option) Video height

and, if there's any way to set permissions to a custom bbcode so i can set the forums where that bbcode can be used.

thanks !
