"This software lets you convert a DVD to a Smartphone and watch it in great quality, with stereo sound and in full screen landscape mode. A memorycard as small as 128 Mb is sufficient to store a full length feature film. ...The software installs an encoding package on a PC with Windows XP, and a free player on the mobile phone. You insert a DVD in the drive of your PC and with only two clicks, the software turns it into a super small movie file, which will play on the provided mediaplayer."
The Pocket PC version of this application is very popular, so I'm not surprised that it has been ported to the Smartphone platform. You can download a trial version that will allow you to burn 5 minutes of a DVD or purchase the full version for $24.99 [Affiliate]
