How do you transfer a dvd to quicktime format?

1

Hi,

I have a client that needs me to put samples of his work on dvd into quick time format (I need to put it up on his website):

1-Im on a mac, which application would I use?
2-If its a lengthy or involved process, do u know of any tutorials?
3-He needs me to put up 6 quicktime videos, what would be the suggested maximum length of time or size for each one ?

Thanks a bunch,
jana
