This article is full of errors, just like most others. Here are some:

So four samples of black and white are sent down in a signal burst,
followed by two samples of blue and one of red, ...
[4:2:0 has 1 each U and V per 4 Y=luminence]

Both MPEG-2 (DVD's codec) and MPEG-4 (likely used in HD-DVD and Blu-Ray) use 4:2:0 formatting
[isn't 4:2:2 an option?]

While dogs can only see in black and white, ... [mammals see in colour]

Here is a better article on Chroma Upsampling Error :

Has anyone rated the major Windows DVD MPEG-2 decoders on quality?
