Aiseesoft DVD to iPhone Converter for Mac is a commercial DVD ripper. You can use this ripper to convert your DVD movies into files that you can later play on your iPhone or any Apple device. The supported output formats are MPEG-4, H.264, MOV, M4V, WebM, and WMV. For best results, I always recommend using H.264 or MPEG-4. Those are two of the most popular formats these days. This ripper also comes with a variety of conversion profiles, which are pre-configured conversion settings for specific devices. There are profiles for the iPhone, iPad, iPod, and AppleTV.
Once you load a DVD movie, the app will list and select all the DVD titles for conversion. You can uncheck those that you don't want to convert. You can convert multiple DVD titles at once and even convert different titles to different formats all at the same time.
Aiseesoft DVD to iPhone Converter for Mac supports subtitles and it has a video editor that lets you trim and crop your videos and adjust some of their properties.
The trial version of this application will let you convert only 5 minutes of video. If your video is longer than 5 minutes, it will be cut in half. That is the only limitation this app has.
