Long, long ago I used beta hifi as a source for high quality music recording. The idea was I could get high quality sound on one tape with a great deal of music, more than any other source available at the time. What about these new DVD recorders for taping big libraries of music (i.e., dvd length over cd length)? Would that work? How much music would go on a recorded DVD and what would the quality be? PCM, dolby digital? Thanks for any info.
