The Region 4 release appears to be better endowed than its Region 1 cousin for a change.
The Region 1 release misses out on the featurette and contains trailers for Love Liza, Owning Mahowny, Punch-Drunk Love and Masked and Anonymous as the sole extra features. The audio transfers appear similar, but the Region 1 video transfer is generally considered mediocre. The fact that Region 1 put the film on a DVD 5 disc (as opposed to Region 4's DVD 9) may be the reason why our video transfer seems much better.
The Region 4 release would seem to be the clear winner this time around.
