DSM-G600, DNS-3xx and NSA-220 Hack Forum

I have a new LCD (Sony KDL46Z4100) that is DLNA-compliant.  I can connect to my home network, and from the TV browse to my DNS-323, see the folders there, but only the photos in one of six or seven folders I looked at were visible to the TV when I was trying the feature last night...for six of the seven folders with images in them I received a "no images found" message from the TV.

Of course Sony support thinks it's a problem on the DNS-323 side. 

Can someone confirm whether the DNS-323, in "stock form" should be able to serve photos to a DLNA device like the Sony TV?  I'm on FW version 1.04. 

Regarding the Sony - they have the DLNA logo plastered all over the place, and it says this in product info:

All 2008 XBR and Z-Series BRAVIA HDTVs are DLNA-compliant.

You already know something about digital living. There’s the TV and digital video recorder in your family room. (And another set in your bedroom.) You have a PC and digital printer in your office, along with a network attached storage device. And you’ve copied all your music onto your portable music player and haven’t had to open a CD case for years. But getting them to talk to each other can be pretty tough. Why is it still so difficult to send digital content from one device to another?

Digital Living Network Alliance (DLNA) is a collaboration of the world’s leading consumer electronics, PC and mobile companies that has created design guidelines for a new generation of products that can work together — no matter the brand.

Think for a moment about all of the photos "locked away" on your home PC that you wish you could access while entertaining your friends and family. Now, thanks to DLNA enabled devices, a DLNA-enabled PC can be accessed from the comfort of your living room or family room via a DLNA-enabled HDTV, where you can enjoy your memories with friends and family, without having to deal with the hassle and non-intuitive "PCexperience".

Or, say you recently downloaded your daughter’s birthday party video from your digital camcorder to your PC. Now you want to share it with your parents who are visiting. Without DLNA, you probably have to burn a DVD of the video or hook up the camcorder to the TV. With DLNA, you can just use your TV’s remote to call up the video on your TV. That’s it.
