Comment 1 for bug 1049828

Until recently, a bug in Unity prevented the integration of such scopes in the lens, but many new Unity features (such as Previews) will be available for it in Ubuntu 12.10, and the next cycle should also offer a new round of features for the lens (thanks to the work done by the Ubuntu TV team). Some of these will probably be available as third party scopes in the Software Center in the next few monhs.

Regarding movie posters and dvd covers, a major issue is the lack of a standard video metadata framework for Ubuntu (without installing big pieces of software such as XBMC ). Some scopes (such as the experimental "Rotten Tomatoes" one) do this their own way, but the Grilo framework being worked on by Gnome should globally solve this and be used by the lens (and Ubuntu TV).
