Latter.

So does that mean the original source has the incorrect aspect ratio and the the 1440 amount of pixels vertically are being scaled down to 1080 by our TV or encoding process? Or is it originally full 4:3 and the editing team crop it to 16:9, which the BBC then essentially upscales back to 1920x1440 for broadcast, and it is then downscaled by your TV?

Where is the change actually being made?

@Spice_Rack:

The broadcast is 1440 pixels wide and 1080 pixels tall. The picture would be stretched width wise to 1920 pixels.

anamorphic - look it up.

The question is not who stretched what and who did the stretching right, but what shape a pixel is.

This has been explained by narf (or plissken, who is in the same league knowledge-wise) some months ago in the "Top Gear in HD"-thread: It's a thing called "wide pixels", basically the same an anamorpic lens does in 35mm film: It's a full-frame 4:3 image that's stretched to 16:9, which makes each pixel a bit wider than it's high...

Its broadcast in 1400x1080, and it looks GREAT.
Thats it.

No it's not.

Seriously, use the existing HD thread. It's there for a reason.
