Hello,

I have a Sony DHG-HDD250 DVR and a Sony DHG-HDD500 DVR. They both use the same remote & do not appear to have discrete On/Off based on model.

I want to be able to use my Harmony 880 to only control 1 at a time.

How can I do this?
Are there IR repeater's/controllers/blasters?
Do I have to put a book in front of the IR receiver I do not want to use?

Thanks!
