Hi, some budget DVR cards only do 320x240 or 320x252 .. (NTSC) ..

Could be the card's limitations, and yes, depending on the camera, it would make a difference.

What card is it and whgat type of cameras do you have?

Does the card have Audio support? If so is it enabled?

Like with the Grovision cards, when Audo is enabled, the capture resolution is limited...

If your cards are CIF card, the resolution can only reach 320*240. If you want to reach 640*480, you have to buy D1(4CIF) cards. But these cards are much more expensive than CIF cards.
