First, you should really use Markup() not Markup_e() otherwise your code 
will break with recent PHP versions:

   Markup_e('leftvideo', 'directives',
     "/\\(:leftvideo\\s+(.*?)\\s*:\\)/",
     "leftvideo");

function leftvideo($m) {
   $video_code = $m[1];
   // ...
}

If your function returns wiki markup, it can call PRR() "PmWiki Redo 
Rules" either before returning the markup, or with the return value:

   return PRR($output);

And the answer after "How can the text returned by my markup function be 
re-processed by the markup engine?" in the page:
