It will not work with that combination.. you can not start with a black, silver or gold and can't end with black, orange, yellow or white. if you upload a pic we can try figure it out.. otherwise try this link 5 Band Resistor Color Codes
Yeah its def. right ndrew.. im not to crash hot with ohms on a DMM but i know that what i said in my post above is the correct reading for that resistor! btw as Things said, 0.5 ohms is still within tolerance range.. which means that 0.33 is correct!
Just touch the leads of your multimeter together first, that will usually show some low resistance value, in your case probably 0.2 ohms. The resistor adds 0.3 to that reading 0.5 - fairly common effect since the meter measures the resistance of the leads too.
