i have a small dvd player which i got in 2004
so wanted to buy a different dvd player
but i want to start buying blu-ray movies also

i was wondering if ALL blu-ray players could play dvd's
if not then which ones and what are the price range
i was asking this because i don't want to buy a blu-ray player AND a dvd player

also do blu-ray players only play in HD TV's or could they play in a fat tv from like the 90'
i have flat screen but its in the living room and i want to put the player in my room and i have those fat tv's
i know that why would you get a blu-ray if you'll use it in a crappy fat tv but i wanna get the blu-ray now so i could save up to buy a hd tv....
