High Def TV vs Regular TV

They announced that the first season of Battlestar Galactica is going to be released in high definition this December. I was wondering how much of a difference there was between standard def and high def tv programs. So I downloaded a high def episode of Stargate Atlantis - Missing. Weighs in at 1 GB file size vs 350 MB for the standard def version. Lets take a look at what this bigger file size gives us.

Here is a side by side comparison of the image quality (Our hero John Sheppard):

The image really says it all, the detail is pretty amazing. You can see John's spiky hair and Atlantis patch clearly in hi-def. Well damn it, now I'm going to have to get some of the newer shows on HD-DVD :)
