Hi,
I ran into the exact same issue with the Samsung DA-E750 Wireless Dock... device appearing and disappearing, playback error messages, etc...
I then decided to try to stream to the Dock using Windows Media Player, and to do that I first had to set-up streaming in WMP.
After that was done, streaming went smooth with WMP, and after shutting WMP down and trying JRiver MC again, it also worked there.
Update 1: my joy was short-lived. Problems with device showing up and disappearing started again.
I think that MC messes the Samsung Dock up somehow. Here's why I think this:
- start up the dock (dlna mode)and start up WMP on he pc
- streaming then works fine
- close WMP and start JRiver MC -> dock appears after a while, disappears, and so on... Playing back results in the error messages as shown above in this thread.
- close JRiver MC and start up WMP again -> impossible to stream to dock anymore
- reboot dock (keep WMP open) -> streaming works again in WMP
I've tried many DLNA-settings in JRiver MC, but nothing seems to work.
Streaming from the dlna server on my NAS (ReadyNAS ultra) also works.
Update 2: did some more tests...
- installed "Asset DLNA" server on my pc, and that works fine...
- Then tried to play to the Samsung Dock with the JRiver MC DLNA server as source, but controlled from my phone with BubbleUPNP.
This works perfectly.
- The moment you select the Samsung Dock in JRiver MC, it disappears and reappears. Playback then stops on the Dock.
- Using the Device Sniffer for the UPNP Developer tools, I notice that the dock disappearing seems to be caused by packets with type "NOTIFY/BYE".
The issue seems to be caused by the initial communication between JRiver MC and the Samsung Dock...
I still wonder why it was working for a short period yesterday...
Anyone who has any clue what is causing this or if I can report this to the dev team? (how to report)
Cheers,
Charles
