No I definitely understand. I just wanted to make sure you are capturing your monitor at no more than say….1024×768. 800×600 everything looks bigger but you have no room to work with!
I just think that would work better than capturing say… 1280×1024.
Are you making a 4:3 dvd, or 16:9? If 16:9 I guess go with 1280×768.
I hope it turns out well whatever you do!
