I have tested this query and MinimServer does return genre information. I don't know why you saw zero genres returned.

Quote:Serento now asks one cheap question before deciding: Search(ContainerID="0", SearchCriteria=upnp:genre exists true, RequestedCount=1).

This query is not quite as cheap as you are expecting. When a search query specifies a range of returned items, MinimServer searches for all matches, caches the query result in memory and returns the requested range. This is because many control points issue a succession of search requests for items 1 to 50, 51 to 100, etc. In this case it is more efficient to do the search once and return each requested range from the cached query result.
