Baby Einstein Dvd's

I am looking to buy Baby Einstein DVD�s and/or CD�s /if you are done with yours..and you think they are good/. Also have a question on what experience do you have with any DVD�s/CD�s for babies, How old the baby has to be to watch them /and for how long/ or shows interest in it. Any kind of advice will be greatly appreciated. Thank you!
