After reading your reply I discovered a way of increasing the res on the second stream (tile view) and that has resolved the prob...thank you for your help..one other thing, there is a setting on the camera to adjust the shutter speed...it's reasonably ok on "Auto" but much better for movement on "Auto (High Shutter Speed)...problem is when I put it on this setting I am getting interference on the picture.similar to the kind of interference you would get with a bad connection (lines across the screen..that kind of thing). I wonder is there any way around this please.
