Can anybody tell me how the Xbox performs as a DVD player? At the mo I have a DVD/SACD player and am thinking of getting a dedicated CD player and an Xbox instead. What will I be missing out on? Can it do multiregion? How does the picture compare to a reasonable DVD player (with the Svideo conector)? Does it work OK with Wide and 4:3 material? Will I get DD and DTS if I connect it to my reciever with an optical link? I don't watch that many movies but would like to keep the flexibility of my current player with different formats. I'm not fussed about zoom effects etc. Also, what do I need to buy to make it play DVD movies? Comments please.
