DH will have it no other way than High Def!!! I guess I agree too, it does look so much better. I guess if you didn't have a high def TV and DVD player it wouldn't matter? From the little I know(DH is the electronics geek in our house!LOL)to fully utilize it you would need to have a HD TV and DVD player.
our videographer just bought a blu-ray system so we opted for this. We are still waiting for it but I am glad that we made this choice, future proof and all that.....well hopefully things change daily.
