Why Blu-ray?Who needs such enormous amounts of data and throughput? What is the purpose behind this? The answer: The big companies want to sell you HDTV.
HDTV is High-resolution Digital Television combined with Dolby Digital surround sound (AC-3). For a complete explanation about HDTV see: http://www.howstuffworks.com/hdtv.htm
HDTV drives on 3 cornerstones; Bigger, sharper and better than your old tv set. Mind you that HDTV is not cheap and it isn't available worldwide for a long time.
With the help of Blu-Ray recording devices it is possible to record up to 2.5 hours of very high quality audio and video on a single BD.

Cool post, Mr. Belvedere. 
Great info on the BD. So, when's the expo on the 130GB CD3?

I thought there were so little reactions, I felt compassion with Mr. Belvedere. So once again: nice article.
Ok. Great article... but... Why are they using MPEG2? We live in a world where MPEG4 has taken over(divx). All they need to do is creat a MPEG4 for super high resolutions(1080p).
Same with audio. By that time we will have DD10.2 or something like it. Audio should be encoded in WMA8(divx audio) or MP3PRO.
