Too bad you can only watch cable TV on a $700 plasma screen TV. Wouldn't it be great if you could use some form of external device, like a DVD or Blu-ray player, to watch movies on it? It would also be nice if you could subscribe to some form of service, like Netflix, that delivered those movies to your house. Alas, you definitely can't do any of that with a $700 plasma screen TV. Just go ahead and return it; it's completely useless now.
