remote help, some buttons not working

[freeballer]

I just upgraded to the beta 3, I am using it on my raspberry pi, model b.
I bought a decent remote off ebay. Some buttons don't work though on xbian, I'm not familiar with xbmc setup so I'd appreciate the help. By default I do not see a lirc install which is what a few forums elsewhere say to configure. To the best of my ability its an arc6 mce remote, probably similar to a gateway/dell model (but there is no actual brand/label on the front). The direction buttons work, so does select and numbers but the mute, volume down, pause, rew/fast do NOT. I'd love it if someone could point me in the right direction. I am just getting back into linux after a year or two...
