This again...
I can't get DLNA/AirPlay working for the life of me. Had the problem, as many of you did, with 4.19.36 but it was fixed by disabling IGMP Proxy (through http://192.168.1.1/index.cgi?active_page=6059). Now with 40.20.1 it again doesnt work and disabling IGMP Proxy has no effect at all.
Anyone else experiencing this? Anyone have anything I can try? I'm at a complete loss.
