I too have no end of problems with DLNA on ARM with my NV+ V2 4-bay READYNAS (which I purchased last week).
I put in the latest DLNA firmware mentioned above, and have tried the "DLNAREBUILDER" twice now. The presentation layer from the NAS is sketchy - folders that used to be there are shown - not all folders present are shown...drill down and it's just either sparsely populated, or altogether missing. I would really like to see an update from NETGEAR. I pretty much exclusively use their prosumer products to run my home and business, and would like to say they came to the table when trouble hit.
At first I thought it was the Sony PS3 that I use as my main media server, but two other DLNA clients (one Android, one iPad) confirmed that the directory structure (database) being presented by the NAS's DLNA function is just plain wrong (exactly consistent with the PS3's hosed directory structure).
NETGEAR - Please push this one up in the priority list! Since I have a media company, this is VERY important to me, and I've already scrapped the "Frankensteined" PS3 media server I built to get the basic functionality for clients.
