That actually makes sense on a level. The pull is like you coming to me and saying "hey, I am here!!" Now, I know you are here, and you can start new conversations with me AND I can initiate conversations with you if I want to. Note, however, that this process of establishing communications is done directly - with a message "hey, I am here" that was sent by you to me. There was no "undirected" communication, as in "is there anybody out there?" (apologies to Roger Waters and Pink Floyd)
Starting with a push, however, means that in order for Jriver to know that the Oppo is there, there has to be a successful
"discovery" conversation PRIOR to the push. To carry forward the analogy: I would shout "is anyone here?" and then you would reply "hey, I am here". Unfortunately, in DLNA/UPnP, that first shout out is an undirected message
, and in network terms that means broadcast or multicast
. As I have said before, I have had numerous problems with broadcast and multicast traffic on wireless networks that I do not have on a wired network, and that problem has interfered directly with the discovery process in DLNA. This has been true for several different wireless routers and access points. I have had no such problems with discovery on any wired network (friends who I help with setup or my own rig). Hence, my assertion that, if you want reliable discovery, you need both the Oppo and the computer running JRiver to be wired to the same network and not be wireless.
