Query: poor audio on discs 3 & 4. Beware!

The DORIAN GRAY and TURN OF THE SCREW discs presented me with the same audio problem described by other reviewers: the actors sound like thier mouths are full of cotton. I played the discs on several different DVD players with the following results: no audio problem on Sony players, inaudible dialogue on Panasonic players. (JEKYLL/HYDE and DRACULA discs played perfectly on ALL players.) Conclusion: DORIAN GRAY and TURN OF THE SCREW discs contain defect making the audio incompatible with some players. MPI continues to ignore the problem.
