This fixed the problem because the horizontal capture resolution is now fixed at 640 pixels. The problem I was getting (and I'm assuming it's the same thing you're seeing) occurs when the tv card is asked to produce a picture that is greater than 768 pixels. If you experiment with resizing the window in non-fullscreen mode, you should be able to verify this. Bear in mind that the height of the window does also have an effect (make sure it's greater than about 300 pixels). > However, I have impression that this image is interlacted and that only > every other frame is being displayed. or so it seems to me, am I wrong > here? I'd imagine that you'll be getting some interlacing (because the tv card is being asked to show more lines [400] than there are in a single field [<300]). Every *frame* should be showing up, however. -- Jonathan Paisley paisleyj@xxxxxxxxxxxxx
