@jaxel i still have the same problem
"A required field called level is missing or has an invalid value."

i try with the update and you still have two bad code on
$db->query_write("ALTER TABLE" . TABLE_PREFIX . "videocategory ADD level int(10) NOT NULL");

and in
$db->query_write("ALTER TABLE" . TABLE_PREFIX . "video ADD timelength int(10) unsigned NOT NULL");

must be "ALTER TABLE " with a space betwen table an "

but the level value is still not working any help will be apreciate
