This Letter shows how these problems can be resolved by a different choice of expansion parameter. The calculations presented correctly reproduce the plasma energy-momentum tensor within the framework of second order viscous hydrodynamics.Title changed; the coordinate transformation between FG and EF coordinates elucidated; version published in PRLHigh Energy Physics - Theorytext
