Try Magic DVD ripper. You can download a free trial version that gives you 15 or more RIPs/Encodes. I used it and was very satisfied. I ended up buying Magic DVD Copier wich enables me to copy all of my DVDs to my computer as full quality. The ripper version will allow you to copy but to also change the video format. I believe the purchase for each was around $40.00. Converting formats puts a huge load on your CPU, so keep this in mind.
