I'm dabbling a bit with cctvs and this is one problem that i couldnt solve till now.  
  
I have tried swapping cameras  and cards (silicon and a locally made dvr card) but to no avail. Switching between 800 x 600 and 1024x768 didnt have much impact that's noticeable.  
  
Is there anyway to replicate tv image quality on a computer monitor?
