Trying to use .htaccess rules to redirect to load FR content w/ a FR domain and EN content w/ an EN Domain

Question

I'm using MediaWiki with mulitlingual subpages.

When I go to "english.com/Page_title" I want to load just that (which is the default)

When I go to "french.com/Page_title" I want to load the /fr subpage, which is "french.com/Page_title/fr"

and here's my current rules:

RewriteBase /

RewriteRule ^[^:]*\.(php|src|jpg|jpeg|png|gif|css|js|inc|swf|flv|phtml|pl|ico|html|shtml|zip|rar|svg|eot|ttf|woff)$ - [L,NC]
RewriteRule ^index.php?title - [L]
RewriteRule ^(.*)\&(.*)$ /wiki/index.php?title=$1\%26$2 [L,QSA]
RewriteCond %{REQUEST_URI} (//+)
RewriteRule ^(.*)/(.*)$ /wiki/index.php?title=$1%1$2 [L,QSA]
RewriteRule ^(.+)$ /wiki/index.php?title=$1 [L,QSA]
RewriteRule ^/*$ /wiki/index.php?title=Main_Page [L,QSA]

Taken from here: http://www.mediawiki.org/wiki/Manual:Short_URL/Page_title_--_PHP_as_a_CGI_module,_no_root_access#Alternate_option_V

I've plays with various RewriteCond's and rules but can't get it to work, always endless redirects or 500's.
