I followed up this issue with D-Link support. The response was that DNS-343 only supports ID3 tags in MP3 files. So if you are hoping to use DNS-343 for streaming audio via UPnP in any other format you are pretty much out of luck. Well, you can still stream but you can't browse your library properly, which essentially makes the whole thing useless. So I really don't see how D-LINK can say that the device supports any other format than MP3.
