Custom post type, permalink, add query variables problem

Yes I did, didn’t help but thanks anyway!
I fixed it by installing the dump environment plugin
http://wordpress.org/extend/plugins/dump_env/

This way I was able to evaluate all existing rewrite rules.
My custom rewrite rule was conflicting with an existing rewrite rule that WP generated for the custom post type by default.

I changed my rule

'kennel/ras/(.+)/(.+)/?$' => 'index.php?post_type=" . $dvd_post_type . "&artist=$matches[1]&genre=$matches[2]'

Now it works as it should!
The dump env plugin, this is going to save me some development time in the future 😉
Thanks!
