I'm having trouble trying to use a Harmony 720 to control a Dell Studio Slim running Windows 7 x64.
The IR receiver is one of the "5070-2584 NEW HP Media CENTER Remote IR RECEIVER" ones without the remote from ebay, and it seems to install properly and appears in the device manager under "Human Interface Devices/Microsoft eHome Infrared Transceiver."
In the Harmony setup, I've tried all of these selections:
Media Center PC/Microsoft/Windows Media Center
Media Center PC/Microsoft/Microsoft Media Center (v2)
Media Center PC/Microsoft/Windows Media Center SE
Media Center PC/Microsoft/MCE-1039
Before I found and tried any of those, the Harmony setup interpreted my first guess as a "Microsoft 1014," so I've also tried that one.
All of these attempts got the same result, which is that none of the remote buttons has any effect in Windows Media Player or Media Center, which I would expect to work pretty reliably.
The red LED on the receiver does flash, but only when I use the volume up, volume down, and mute buttons. None of the other buttons on the remote gets a response from the LED. Even though the LED flashes, the volume buttons have no effect on WMP, MC, and the system volume.
There is a Logitech diNovo Mini also plugged into the system, but removing it doesn't seem to make any difference.
Am I missing something obvious in the setup? If this receiver isn't a good option, can you suggest another one?
