Query: IT WOULD HAVE BEEN A BETTER PRODUCT

THE DVD PUBLISHER HAS NOT MADE A GOOD JOB OF EXPLAINING THE OPERATION AND SPECIAL FEATURES OF THE UNIT.IT WOULD HAVE BEEN VERY USEFUL FOR USER OF R16 IF PUBLISHER COULD HAVE TAKEN THE TOPIC SERIOUSLY. THERE IS NO MENU, NO INDEXING,SOUND QUALITY OF RECORDING IS POOR AND IN STEREO LOW QUALITY.BUT SOMETHING IS BETTER THAN NOTHING
