Launch app with UPnP or otherwise

[jvottele]

Hi,

I have been looking for the answer on this question, but could not find it anywhere:

Is it possible to launch an app that I installed on my Samsung ES5500 from a UPnP command, through MainTVAgent.
Or it not, otherwise from a network device (PC, Smartphone) etc.

I managed to start the browser from the UPnP command urn:samsung.com:service:MainTVAgent2:1#RunBrowser, but now I want to start YouTube or (even better) my own app.

Thanks!
Jan
