Default Why do people say things like this???

I was on EngadgetHD and I was reading the resonds in the "Michael Bay's format war conspiracy theory: it's a Microsoft fix" and I came across this:



He is qouting this statement
HTML Code:
"The problem is whenever the same movie is available on both formats, it's
always using the same encode, one that has a low enough of a bitrate to
work on HD-DVD. I'm not aware of any movie released on both formats
getting the higher-bitrate encode that blu-ray is capable of. Of course,
blu-ray exclusive titles get to enjoy higher bitrates, but then it's harder to
compare."
This is his respond
HTML Code:
Ghods, this is tiring.

The reason those BD-exclusive disks needed a higher bitrate is becasue they
are encoded in mpeg2, which is about 20 years old now. Using a modern
compression system results in both better output image and a lower transfer
bitrate.

You have the cart before the horse: the bitrate on HD DVD was set based on
the efficiencies of modern compressers. The extra bandwidth on Blu-ray is 
largely used for uncompressed audio and poorly performing algorithms like 
mpeg2. In short, it is wasted, or used to keep manufacturer's costs down by 
not paying royalties for the good stuff.
I just can't believe what some people are saying out there.
