It has emerged that the new DVD release of "The Great Race" has an audio problem that totally ruins the opening credits. Boos are supposed to accompany Jack Lemmon's credits and cheers for Tony Curtis. This has been incredibly reversed so it's boos for Curtis and cheers for Lemmon. Also on the "Wizard Of Oz" the wrong track has been used for the "Jitterbug" supplement. The piano choreography rehearsal track with Donna Massin standing in for Judy Garland has been inexplicably used instead of the full, final version intended for the film with orchestra and full cast. I believe these discs should be corrected so that customers can enjoy these the way they should be enjoyed. The more serious problem is in "The Great Race" where the film itself is literally ruined by this glitch whereas the "Wizard Of Oz" problem is in a supplement albeit a problem that forces me to rely solely on the old "Ultimate Oz" Laser Disc boxed set for whenever I want to enjoy the supplementary material.
