  I think this is a very presumptuous statement.  I am looking forward
  to recorders which encode both the audio and the video digitally.  Digital
  recordings make possible a wide range of error correction and detection
  schemes to remove those annoying glitches which are present in all 
  commercial analog recorders.

  Not true!

  ah!!!
