I would like to know as well. It's a shame there isn't a good working Netflix plugin for 1.3. Atm I've been using Windows 8's Netflix app which works ok. but I'd prefer to use a Mepo plugin
I use this http://www.itsjustwhatever.com/2012/12/19/windows-8-metro-app-launchers/ and launch it via the Multi-shortcut plugin it's pretty straight forward. Only thing is the Netflix app requires a mouse to navigate around. I use my Android phone and the gpad plugin to get around this for now so I don't have to use my mouse. However you can pause and unpause with the mce remote. Just can't remind or fast forward. One other thing you can hit the clear button on the mce remote to exit the app. Hope this helps!
I know that my Netflix plugin was working fine until I had a database problem a couple weeks back and deleted it to generate a new one. I haven't had Netflix work since. My only thought is that the new setup requested a new key, and they're not giving those out anymore.
I'm not hopeful that new Netflix plugins will be possible without using the Win 8 app.
But if anyone who actually knows about this stuff cares to chime in, I'm all ears. My only credential is a grasp of the English language. I've got absolutely no technical expertise in the matter.
