For those of you still wondering about the difference between the two high definition broadcast standards, here is a simple explanation. I have uploaded this video in better quality, because old one is only 240p and we can't see details which are important to understand things. This video was made in 2007 and posted on technologyevangelist.com. So that some informations can be bit outdated, like mentioning HD-DVD, but main topic is still valid and not much has been changed since then.
