Before you give up on the built-in remote profile, there are a couple things you can check:
- Is your IR Blaster cable working ? Here's a link that tells you how you can test it:
- Is the IR Blaster in the right spot ? Placement is critical, sometimes it can be hard to find the best place to put it. If the IR cable is verified working and your QIP2500 is responding to the physical remote, you might simply have the transmitter head in the wrong spot.
Hope this helps, good luck !
I agree those are the most likely areas of problem, but if you have no success then most Motorola boxes use the same code so you could try the Custom Remote at http://www.hifi-remote.com/forums/dload.php?action=file&file_id=6586 to make sure the built-in remote is not the problem.
