I need to provide clients a physical copy of the video and audio which they can access with a pc, and retain physical and digital copies myself. The video does not have to be of the best quality, but the audio has to be discernible. Does anyone in the tech-savvy Slashdot crowd have any suggestions for what the best format (physical and digital) for this type of application is, and are there any suggestions of appropriate equipment for video and audio that is also relatively inexpensive? Is there a good way to de-couple audio from video and store the audio as a separate entity? Any help would be much appreciated."
