Solutions to the Frustrations of Video?

Re-Torque asks: "In our organizations, interviews with perpetrators of crime (child abuse, rape, etc), and with victims, are conducted by expert interviewers and are recorded on videotape or DVD (with back ups). These recordings are legal records. They are archival records, but they are also used in the courts and in other aspects of the legal process. We have encountered problems with newer VCRs and DVD recorders. As long as the tape or DVD is played back on the same machine, there is no degradation of audio and video quality. However, when played back on any other machine, the quality of the recording is substantially degraded. We have been told that this is to frustrate illegal copying, but in our case, it frustrates the legal process. In your experience, is the problem in fact one of design of the machines or are we doing something wrong (i.e., some settings we should change before recording)? Are there any machines available that are not crippled in this way? Or are there other strategies we might employ to resolve this problem?"
