I'm going to buy this HD DVD from amazon :

and I have LG Multi DVD Writer internal device in my computer, will it play the movie ?
I doubt so! You need a HD DVD player. If not, a hybrid kind of TV that accepts playing movies and music from iPhone or memory cards would be your other option (was told it saves more electricity than conventional TV)
