I don't know if I'm describing this properly or if this is the correct place to post. If it is not, I apologize in advance.
I am running a Windows 7 Ultimate (SP1) computer with MC 16 latest build. I have tested for this over a number of builds and also with MC 15. The problem persists for me. When I first start MC, or if I restart the DLNA server, then my WDTV can "see" the server. After it has been running for a while, it stops seeing it when I go to Video-->Media Servers. Out of frustration, and in order to try and determine whether the problem is in MC or WDTV, I enabled Windows Media Player server on the same computer. IT ALWAYS SHOWS UP, even when MC does not show up. I've got multiple WDTVs on my network and they all seem to share this behavior, but it isn't a permanent condition. If I keep going back and forth from Video-->Media Servers to Video and back, it will eventually "see" the MC server again.
Perhaps if I understood what has to happen for the WDTV to "see" MC I could forumulate some test to figure out what is going on??
On a second note, which may or may not be related, I previously was able to select and watch m2ts (BD) files on my WDTV using the MC server. This seems to have changed, perhaps when I installed SP1 on the computer. Now, when I try to play them, I get an "unsupported format" error on WDTV. If I switch to the WMP server on the same computer and select the same BD file, it plays just fine.
Any help or suggestions as to things I should check out would be sincerely appreciated.
