       I do NOT believe this to be true. I'm sure there are some video 'techs'
  out there who have some idea on what HQ circuitry is and what it adds or
  subtracts from a VCR.

       My opinion is that if you have a lousy recorder in the first place then
  HQ won't help your situation anyway. I'm sure the places that make quality
  VCR machines add HQ for the 20% higher resolution in the picture quality.

       It looks like we're both only talking about a couple different VCR
  machines here. Does anyone else have experience or knowledge of HQ circuitry
  and its effect on picture quality with other machines???
