Just a question... are you doing velocity control? If so, I'm guessing you're running in the 39.37Hz (25.4ms) loop? Is this enough resolution?

By my calculations, you can have an absolute maximum velocity control resolution of 0.39ft/sec. Is your robot really really fast? Hence the low res encoder?
