  The bosonization of the $S=1/2$ anisotropic two-channel Kondo model is shown
to yield two equivalent representations of the original problem. In a straight
forward extension of the Emery-Kivelson approach, the interacting resonant
level model previously derived by the Anderson-Yuval technique is obtained. In
addition, however, a ``($\sigma$,$\tau$)'' description is also found. The
strong coupling fixed point of the ($\sigma$,$\tau$) model was originally
postulated to be related to the intermediate coupling fixed point of the
two-channel Kondo model. The equivalence of the $\sigma$,$\tau$ model to the
two-channel Kondo model is formally established. A summary of what one may
learn from a simple study of these different representations is also given.
