Files deleted from ReadyNAS Duo still show up on DLNA client

I have a Samsung Smart TV with a built in DLNA client. When I browse on my ReadyNAS Duo for the video files I have stored, several files that have been deleted from the ReadyNAS still show up on the file listing. I've stopped and started the ReadyDLNA services per Netgear support but that didn't work. Anyone else have any suggestions? Another symptom of possibly the same problem is that a few files on the ReadyNAS Duo don't show up in the DLNA folder lists.
