First I would like to thanks for MarcosQui. It is an excellent work I love that skin. Actually I am using Boxee 1.5 and also XBMC on my PC. It is not easy for me to decided if I prefer Boxee or XBMC because I love the option to view trailer before the movie. I am trying to figure out how to add this on XBMC but is not easy ;( If anyone know how to stream movie trailer on the same folder that the movie, please tell me. If I found this I will definitely use XBMC instead of Boxee.
There is actually an addon to do what you want.
Please check on this :
XBMC is awesome!
