Not all HD is created equal.  Most cable and satellite HDTV programs are broadcast in 720p (also known as 1080i).  And on cable systems, some HD channels aren’t even 720p, they are compressed because they can’t fit all that data through the cable.  So you aren’t even getting the full HD effect.  Sad, but true.  HD takes up alot of bandwidth.

Blu-Ray has become the most popular HD format for DVD’s.  More and more companies are now making DVD’s for blu ray, made by Sony.  So if you are thinking about getting an HD DVD, then get a Play Station 3 and you’ll automatically have a great blu-ray DVD HD player.  Not to mention you should buy Call of Duty 4 and play it in 1080p mode (FULL Hi Def) on at least a 46″ TV.  Simply Amazing.  I think my accuracy went up when I did.

Not all games for the PS3 are in 1080p.  For example, one of the top games, Oblivion 4, is not in 1080p.  It’s 720p.  Which means it has 30% less detail than it could.  Hopefully the next game in that series will be FULL HD.  So, it’s important to check the back of the box to see what the graphic detail is.  Lately I am addicted to full HD, and fortunately and amazingly COD4 is Full HD (1080p).  Be prepared to be sucked into hours / months of game play should you buy Call of Duty 4.  You have been warned.

Finally I also upgraded to a quad core PC with 4 gb and rocking graphics card.  This new system smokes.  Should have upgraded a long time ago for sure.
