Urxvt + vim arrow keys in insert mode problem

Question

There's this annoying problem I've been experiencing for a while now that I haven't been able to fix.
I'm running urxvt-unicode-256color as my terminal emulator. When I'm using vim in insert mode, accidentally hitting the arrow keys inserts A B C D or into the file. I don't use the arrows keys, but accidentally hitting them can get really annoying. I've read all sorts of ways to resolve this and none of the seem to work. The only way I was able to get around this was to set $TERM to be xterm, but that seems like a weird fix for this.
Is there another way of solving this?

Map the keys in vim to something useful or to nothing at all.
BTW, I have the same setup and my cursor keys result in movement like hjkl, so:
- check if you're using vim and not vi,
- change your settings in .vimrc.
I've already mapped the keys to do nothing. But it doesn't seem to work. I'm using map and imap, I've also use set t_ku, etc.
How do I check if I'm using vim as opposed to vi? I've already installed the vim package.
I have set nocompatible in my .vimrc but it doesn't seem to do anything.

My term vairable is already set to rxvt-unicode.
Set it to 'rxvt-256color'
