Thank you for a reply.
I know about very small set of supported formats (unfortunately). For now I am converting my favorite movies to MPEG-II - with subtitles converted to video. It works well and even display performance is good.
About that PS3 - working on it
)) it needs some time to convince my wife
Year ago I was looking for D-link DMA player at our stores (no success) but PS3 looks like much better choice ATM - I am only not sure about that optical audio out it has is a good idea.
One more thing about videos. Not sure whether it is a Syno feature or Phillips problem
I do not see any meta information at Phillips file listing. Not even filename - filename shows after a while in right part of screen with filename, but long listing with all media files is empty - just icons.
Is there some way how to tell Syno UPnP software that this video has some meta information? Some INFO file or anything. I did not find any information about some standard for information tags in MPEG-2 files.
Now I see both synology servers.
As DS-508 has two network interfaces, UPnP surprisingly binds only to second one (or in my case - maybe it changes after every reboot, not sure).
At this moment my DS-508 interfaces are connected to different networks and my DMAs are in network connected to Interface 2. So I had to switch cables and IPs and works for now. I see both Syno servers in Phillips source selection menu.
