If you'd like to watch your entire DVD collection on your cellphone (or even your new PSP, ipod, iphone) - but don't know how - give 3GP Converter a try.
3GP Converter is a practical tool which allows you - in as little as three clicks - to convert all types of videos to 3GP, the format compatible with most multimedia capable cellphones, or MPEG-4 for PSPs. By default, the program includes different configurations for modifying the quality of the video and/or sound, and for optimizing the size of the resulting file: 3GPP + AMR, 3GPP + AAC, MPEG-4, SD-VIDEO, 3GPP2 + ACC, etc.
All in all, 3GP Converter is another option to try out for converting content to play on your cellphone or PSP.
PS: Not my work,just a VERY good tool i found. Supports multiple languages such as Chinese, German, Spanish, English, Japanese , Dutch, French, Italian, Swedish, Catalan, Esperanto,and traditional Chinese.
