Just got a TP-Link router with a built-in DLNA server, but it's not working with my Roku 2 XS (build 9044) Roku Media Player app (4.1.1507); I'm not sure which device is the problem.
First off, I've got a couple of MP4 video files on the router's USB storage. Roku Media Player app can see the router's DLNA server, but it thinks that they are audio files. That is, when I select to view video files on the Roku, it says no compatible files found; when I switch to audio there they are.
If I change the file extensions to M4V, now Roku Media Player properly recognizes them as videos. But when I click to play, it just says "retrieving" for a while, and then "server connection error".
Any tips or insights?
