I use DVD to iPhone Converter download at http://www.oursdownload.com/dvd-to-iphone.html It works pretty good .
why buy? handbrake is the best. or visual hub if you are planning in spending money
Quivic from Wide Angle Software ( http://www.wideanglesoftware.com ) is perfect and simple for the job at only $19.99 it is better to have some dollar recognition for a good code than a free and therefore sometimes suspect utility.
I suggest you take a look at this comparison chart and review: http://www.dvdtoiphone.net/review.html They tested the conversion speed, output video quality, stability, formats supported and functionality, etc. Related guide: http://www.dvdtoiphoneconverter.com/guid...
