Permalink of a custom post type - wordpress

Question

I am trying to get the link to a custom post type - Video. I have achieved this by doing:
get_post_type_archive_link( 'video' );
This returns http://mylink.co.uk/video which is brillant and exactly what I am looking for. However, when I click onto a custom post type category for example...LIVE and it loads the filtered results, the script link using get_post_type_archive_link( 'video' ); now changes to the LIVE category link showing http://mylink.co.uk/category/live/.
What is wrong?
UPDATE
function custom_post_type_video() {
$labels = array(
'name' => _x( 'Videos', 'Post Type General Name', 'text_domain' ),
'singular_name' => _x( 'Video', 'Post Type Singular Name', 'text_domain' ),
'menu_name' => __( 'Video', 'text_domain' ),

);

}
// Hook into the 'init' action

I don't know why is it so. I read the code (both yours and WordPress' source code) and didn't find why is it so. I can tell you only two things that might or might not be helpful:-
First
This line:-
register_post_type( 'Video', $args );
should be like this:-
register_post_type( 'video', $args ); // small v
Second
One quick and dirty workaround that you can do is to 'hard-code' the video post type archive link. Try inserting this code in your functions.php:-
function video_post_type_archive_link( $link, $post_type ) {
if( $post_type === 'video' ) {
$link = 'http://mylink.co.uk/video' // <-- this should be link to 'video' post type archives
}
return $link;
}
add_filter('post_type_archive_link', 'video_post_type_archive_link', 10, 2);
Now, whenever you'll call this:
get_post_type_archive_link( 'video' );
You'll get:
http://mylink.co.uk/video
Only for video custom post type.
