In embedded videos (or Flash apps in general) you can specify the width and height in the "WIDTH" and "HEIGHT" parameters of the <OBJECT> tag. But do not forget the space occupied by the controls (button bar, etc.)!
Eg. in case of a Google video the player consists of a video pane and a control bar. The latter takes a fixed 27 pixels in height. So if your video is 160 x 120 and you want to embed it by scaling to double size (without distortion of course), then you have to specify a width of 160*2=320 pixels and a height of 120*2+27=367 pixels.
