We have a Sony Bravia LCD HDTV so enjoy watching anything in HD over SD obviously. I heard there was no noticeable difference between the blueray DVD and "standard" 480i DVD but I find it hard to believe.
I have 40" Sony Bravia LCD TV.
I also know difference between 480 and 1080. I'm an Engineer.

But is the extra cost worth it ?! I'm not spending my hard earned cash on something thats possibly over-rated..
