help with custom htaccess rewrite rule for page

i have a page in wordpress called “video”. its page id is 6, and its slug is “video”

in my theme ive set it up to show content based on GET variables

here is the URL rewrite im trying to set up:

heres the original URL with the GET variables inside:

mysite.com/video/?video_id=102230&video_title=FC+Emmen+v+AGOVV+Apeldoorn&video_src=MTAyMjMw

heres the URL i want it rewritten to so it can be indexed:

mysite.com/video/102230/MTAyMjMw/FC+Emmen+v+AGOVV+Apeldoorn

heres my htaccess file that is not working:

# BEGIN WordPress
<ifmodule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
RewriteRule ^video/(.*)/(.*)/(.*)$ ?page_id=6&7video_id=$1&video_src=$2&video_title=$3 [NC]
</ifmodule>
# END WordPress

what happens is, when i try and visit mysite.com/video/102230/MTAyMjMw/FC+Emmen+v+AGOVV+Apeldoorn, it simply automatically goes to mysite.com/video and removes everything after /video

edit – now it is not removing everything after /video, but its telling me “Nothing found for Video 102230 MTAyMjMw FC+Emmen+v+AGOVV+Apeldoorn”
