There's a lot wrong with UPnP/DLNA but you would need to direct your questions to the maintainers of those components with exception being UPnP Browser (djmount) which has been unmaintained for long time so any issues with it are unsupportable. Generally I don't like having long since unmaintained components in the project that generate support issues and so at some point it might get dropped.
