Obrigado, James, fiz novos testes, e estando setado o áudio e o vídeo para o Receiver, com o projetor ligado, estou conseguindo ouvir as respostas, via TTSSpeach norlmalmente.

Vem ai comandos para Media Portal, bom avanço este, apesar que gosto muito mais do XBMC.

Unfortunately MediaPortal commands will be limited to simple button presses at the beginning.  No plugin exists yet that would allow us to request music, or video.  I may be able to create a function for music later on, and we will be able to jump to a movie in MovingPictures via keyboard emulation only.  the TVSeries plugin for MediaPortal doesn't even support jumping to a letter.

So techinically there is nothing new here except that you can send button presses directly, instead of having to use EventGhost.

If someone has experience writing plugins for MediaPortal maybe they could help.

moving forward to version 0.84...
