The issue is with these two:
http://c6c18eb4180c/lib/js/jquery-1.8.3.min.js
http://c6c18eb4180c/lib/js/swfobject_v2.2.js
Obviously, c6c18eb4180c is the container's ID, also used as the hostname by default.
You need to check where that's set under /opt/kaltura/app/configurations
Also, check the kaltura.delivery_profile DB table. This has nothing to do with loading the KMC but if the host defined there is wrong, playback will fail.
