If I buy a movie from Amazon on demand, where they send it to you over the internet, can I record it to a dvd to play on the tv or does it have to stay on my computer? Can I use it on other computers by signing into my account or do I have to only use it on one? Also, if you use the rental instead of purchase at amazon, how do they keep you from recording it? I wouldn't, jsut because the six or ten buck difference isn't worth my self esteem, but I wondered because I can see the kids asking if it was okay to do or their friends telling them it was and them believing it. thank you esp would fall into that trap. Thanks.
