how do you use the accumulation buffer... how i'd like to use it would be: DrawToBuffer at 0.1 alpha so you can see through to the nine before this tenth.. DisplayBuffer.. but im not sure how to use it :/ no mater how much i try it returns no effect.. however they're examples work fine..

no, it's next to impossible to do motion blur using the accumulation buffer and get a good effect.
The acum buffer is pretty limited in what it can do, not to mention slow.
If you want motion blur it's better to use something like FBO.
