1st) I ripped a whole dvd to mp4 using a program named dvd fab, 2nd) then I intern took a program called Total Video Converter  & encoded it to .3gp & (or) .3gp2 because on my Samsung Finesse that is the only video format that I have got to work & it works very well. I put stargate atlantis first dvd on it & it looked good & even sounded good. Total Video Converter is the only one that I found that actually worked for the phone & a lot of people were writing good things about  Total Video Converter because I tryed around 5 other ones & they did not work, so if you are looking for an encoder use (  Total Video Converter   ) & if you want to rip a dvd to a video file before dropping it into Total Video Converter , then go get dvd fab, I promise you all that you will be very happy for doing it, but know that both of these are not free, but you can find them on mininova , you know torrent downloads & if you do not know what that means, you may as well goto the sites of the software makers & purchase them, all you have to do is google dvd fab & then Total Video Converter. Infact here are the links 1st dvdfab  http://www.dvdfab.com/  & then for Total Video Converter goto http://www.effectmatrix.com/buynow.htm  or the main site at http://www.effectmatrix.com/  oh & if you want both programs for free, then goto this link I put them together for you all in one & also I included full version of Winrar zip file ( JUst follow the direction on how to install in the txt files inside folders.
