Ok, after a few hours of troubleshooting, I've pinpointed the issue and can recreate it at will now.
Basically, if I dynamically create and write to a texture that has a different aspect ratio than the viewport of the game, it fails...that is, I get this crazy amount of blur as if I was flying through my scene very quickly. If the aspect ratio of my texture matches that of the game viewport, it looks great...only the moving items in my scene are motion blurred. Weirder still, if I export a Web or Stand-alone build were the aspect ratios of the game viewport and my texture do not match, the first "render to texture" action fails, but then the camera itself seems to adjust it's aspect ratio (which changes the view of the camera) and subsequent "render to texture" actions pass (though, again, the view of the camera has been altered so I shouldn't refer to this as "passing").
I have a simple test project that I used to troubleshoot this; I'd be happy to send it to you to help you troubleshoot this. (I'd rather not post my files here, however.)
Thanks, and I really hope you all will be able to help with this.
Btw, I'm on Mac OSX Mountain Lion, Unity 4.3, and this issue exists whether I am running other effects or no other effects.
