Input:
User Review: This unit is designed to just play dvd (and other compatible optical media)
with some basic functionalities.  Daewoo put every effort  to reduce the
price after that.  The cables included in the unit tells you how cheap it is.
The remote controller is badly designed.  It easier to operate directly to
the unit w/o using the remote.  The picture quality is better compare to
my 10-year old panasonic 4-head.  The sound quality is low. I hear too much hiss and jitter.  Maybe this is because the volume control  has a
problem (I mean the unit I got happened to be defective).  In short, don't
expect too much. The product is cheap because there're reasons, usually
sacrifycing quality or reduction of quality control (i.e. just ship whatever
they made w/o checking  defficiency.  If a consumer complained, then just replace it).  Anyhow,
I decided to return this unit because the screen periodically change the
brightness which  became very annoying  after a while.  (this symptom did not go away by
changing the system settings, e.g. screen saver -> on/off).  I pay more for quality.
