Also, iPod Touch and iPhone displays are both widescreen (16:9)
The touch screen (480x320) is actually not quite your widescreen - it's 13.5:9
I notice the difference when viewing 16x9 widescreen broadcast that I have captured with my EyeTV Hybrid and converted to iPod use; the station identified 'bug' is at the edge of the touch screen while on my widescreen TV it is not at the edge of the frame.
