I'm in the same exact situation. Mine is older, found on ebay and works perfectly except it seems to process button presses just slow enough to be aggravating.

As usual, tech support can't admit anything and bring themselves to say "Your remote just sucks," but I think that's the case because any other MX-3000 I've tried has been great and has worked just as fast as any of their other remotes. Hate to say it, but I think we both ended up w/ a first generation lemon. I've bought about 60 electronic items now on ebay and this is the first I have ever had trouble with. Too bad I left feedback before I fully tested the item.

I was actually thinking about using it in an audio only situation and just using for source select and for favorites, something that doesn't require rapidly repeating button presses. Good luck.
