The following is a list of software titles available that will allow you to convert your DVD's into MPEG-4 format playable on your iPhone. Beware of products that claim to be FREE (outside of what we tell you). Some companies bait you with "free" software and use a watermark making the resulting conversion useless.
Videora appears to be the most highly recommended tool for this purpose.
Please send me a PM if you feel there is an app I should include in this list.
If you'd like to start a discussion on a particular app, please create using subject: Official Using {INSERT PRODUCT NAME} for DVD to iPhone Video Conversion and then reply to this message so I can add a link from here.
These threads will not be created for representatives of these companies, especially those who have spent the bulk of their time spamming the EIP forums. They are intended for members of this forum and will help keep a sense of organization around the hot topic of iPhone to DVD video conversion.
This discussion thread is not to endorse or recommend any illegal copying or sharing of copyrighted materials. It's for members to discuss how they are converting DVD's they own in a format playable on the iPhone.
Questions, comments... send me a PM.
