well i bought a dazzle dvc 100 last week because the quality looked not too bad

so i got home set it up i play on a hd tv and use a composite cable with my dazzle

everything is fine until i connect the dazzle to my laptop

it makes my tv screen blurry and i get fuzzy black and white lines going across the screen

have a look at the quality here [ Register or Signin to view external links. ]
