91. You should quit while you're behind.
> yet you said that analog video NEVER has any pixels.

I most assuredly did not state this.

I said that analog TV sets and the analog NTSC standards do not have a fixed horizontal resolution. You state that they do. You are wrong.

VGA content can be transmitted over an analog or digital interface, but it has a fixed horizontal resolution. The two are not mutually exclusive.

Unless you are using HDMI for your interface, all communication between your DVD player and your TV set is analog. Whether your TV is analog or digital (plasma or LCD) is where the difference comes in.

A digital display (fixed resolution) can only display video in the display's native format, so every single signal that comes in needs to be scaled and interpolated unless it is an exact match (unlikely). This is why every single digital TV sold today has a scaler/interpolator.

An analog set connected to a DVD player takes the fixed resolution (480 X 720) of the MPEG2 encoded image and displays it in standard NTSC format, ie 525 horizontal lines.

Sorry, there's just no way around that.
