playback of containers

[adrian]

I'm curious about how playback of a container works in uPNP because of the behavior I'm observing from my control point, the Olive ONE.

They added the ability to play back containers, which was previously impossible. But it only worked to a depth of 3 levels. So it seems that it was searching the tree to make a play list based on everything it could find. They have now increased the depth of the search. I selected "genre->Finnish" to get to a container with 12 tracks in it, but when I asked my control point to play it, it assembled a list of 15 copies of the 12 tracks, like it found it multiple different ways in its search.

So here's my question: is there some natural support in uPNP for playing a container? In other words, are the people programming my device idiots? It seems to me that if they are searching the tree there's no way to reliably get the right result.
