Before I try this.. I just got a Harmony 650 for my wife, I would of gotten a 700 or higher remote if I thought that cost of the added device was worth it. (I am use to remotes with more than five devices like the 880 and the 'China Clone 688' {From eBay, which at time of purchase I did not know it was not a true Logitech/Harmony device, but Logitech allows this device to access their data base luckily}.)

But I find that I am one device short.. my HD-DVD player ..as it will play DVD+R home made DVD where my new BluRay player will not.. but back on topic..

My TV is a Toshiba, can I add by learning the key presses for the HD-DVD to the TV's library of commands??

Then set-up a generic setting to watch HD-DVD to have my receiver and TV switch to the correct inputs / volume control?

(PS: or is there any way to combine two DirecTV DVR's as a single device and just change the device code in the remote via macro?)

(I was able to do a like combine device function with JP1 remotes, in the past!)
