Sucks to see the amulet being discontinued, I like the remote, but I use it with eventghost, it does get annoying when it sends out a different IR signal when pressing the button multiple times, or having it send the record button IR signal when I'm just turning the volume up, but the microphone benefits outnumber the problems
Sadly, I wasn't able to get USB-UIRT+EventGhost to work with volume changing on my Pioneer receiver. It changes one point when I press the button, but won't change fast while I hold it. So I still need my receiver remote. 
there are couple different things you can do to get around this
1) is what jitterjames said, having the receiver hidden or in another room, so its not seeing the IR signals from the remote and IR blaster at the same time (the best option, but not always doable)
2) instead of having it adjust the volume by 1, have it adjust by a bigger number, like 3 at a time, this is done in eventghost by using a .55 second wait and then adding the volume up or down commands 3 times,
3) create a new macro in eventghost, start with a .55 second wait and then add 10 volume Up or Down actions, then add "Jump if double pressed" to the bottom of your regular volume macro and have it execute your new volume macro, then to turn the volume up or down by ten you would just hit the button twice in X amount of time and it would turn the volume Up or down by ten
the only one of these options that will give you the same feel as a normal remote is the 1st one, the other ones work but take a little bit for people to get used to,
