Hi Franco,
I just installed a 1110 decoder onto VISTA media centre after my old DSD910 died.
I comply connected the decoder to my PVR-150 capture card and stuck the Microsoft IR blasters in the center of the face plate using clear double sided tape.
I then ran through the setup wizard and ended up having to teach media center the IR codes as the settings it detected didn't work for changing channels.
If you have any specific question let me know.
