Other apps (Mubi, etc.)

I have a subscription to Mubi, and I’d love to be able to watch it through the WD TV Live. But, so far only really BBC iPlayer and a bunch of rotten-looking video apps.

So, is it a matter of just waiting and praying that someone at WD or Mubi decides to branch out on the things they offer? Or are there any homebrew ways of doing it? All it really is, is a skin for a website, I suppose.

Your post sounds more like a good Feature Request; best placed in the Ideas Exchange section. This way someone from WD will be sure to see it and will allow more users to support your idea. However, I would first search and make sure that there are no other active Feature Requests suggesting the same or similar improvements. If there is, then you could add your post and vote on it.
