help!I want a DVD ripper

hi all, I am newbie of the circle of encoding DVD, sorry for my “stupid” question. Recently, i am searching solution to play DVD on my macbook and iPhone because I really want to watch my video no matter anytime, anywhere. I googled a lot and found some passages and software, this passage caught my eyes: http://www.videoconverterfactory.com/tips/dvd-grabber.html but something seemed wrong according to its steps, i found my DVD can not be read but i can play them on VLC. Anybody knows the issue? or do you have better idea? Thanks a lot.

I believe I used anyvideoconverter for a while to do it and i think I also used wondershare dvd ripper. It has been a while since I had a mac

Use MakeMKV, it is free while in beta still and works great. Just look in the forums on the site for new codes to activate it in the announcements section. The dev will keep them posted there.

You can then encode with Handbrake

Or just give up and find a copy, you know where, that is already ripped for you.
