I recently got the EX645 (2012). I've installed PMS on one of my computers and the TV can see the server and browse movie files. However, I can't watch any movie, when I try to Stream the tv just hangs (but I can see that the PMS buffer fills up). I'm trying to stream 720p MKV files.
I have an Asus n56u router so I don't think that the network is an issue.
I've forced the PMS to identify unknown renderers as Sony Bravia but still nothing works. Any ideas how to go from here?
