Didnt we supply you a DVD changer and PC for this job that you crashed by reformatting it and we had to set it up again ?

Its clear your out of your depth here. What IR receivers are included with the matrix and where have you positioned them. Give us a call tomorrow and we will try to help wherever possible. Ask to speak to Adam.

I don't know the Smart E system but what you have are standard installer problems that we deal with every day.

You should stick to IT !
