Mach 2's anamorphic 1.85:1 transfer contains nothing particularly impressive or noteworthy. The colors have poor definition and lack the clarity inherent on most digital transfers. The entire transfer is grainy and contains a significant amount of defects on the print. It resembles a mediocre video transfer and adds another element to the problems of this disc. An irksome problem on this 5.1 channel Dolby Digital transfer is the extremely quiet dialogue. Also, the sound levels vary throughout and require adjusting during the louder action scenes. As with the image transfer, the term "digital" should be used loosely because this sound field lacks most of the qualities of usual DVDs. This disc also contains a 2.0-channel Dolby Surround track that contains less power, but actually is less annoying than the other track because it keeps a more steady sound level. Mach 2's only substantial extra is an enjoyable feature-length commentary from director Edward R. Raymond and actress Shannon Whirry. While the nature of this film makes an in-depth discussion impossible, both of them have a lot of fun talking about the picture. Raymond totally understands the tenets of the silly action genre and often mocks his own films. Whirry asks him some fairly stupid questions, but they work because both of them have a nice chemistry. The comments are fairly scene-specific, but they're mildly interesting given the poor level of this film. This disc also features the theatrical trailer and brief biographies of the main stars and Raymond.
