I just bought my WDTV Live and I am very happy with it. However it has a strange bug: it displays pictures just fine but only for a while. After that it only displayes the thumbnails and when you try to see the picture it hangs on the waiting animation. This goes for Twonky, PS3 Media Server, Network Shares, Flickr
On the other hand youtube and movies work just fine. I realy like beeing able to see my pictures on TV .
The only workaround untill now I found is to reset it to factory defaults and redo the settings back. Then it works again for a while.
