I have tried a lot of tools to convert my videos for PSP. I found a tool that for me it's the best tool that I've used. It's pretty easy to use with profiles, fast and reliable. Here some description: SUPER © IS UNIVERSAL as it supports a wide variety of input/source file format to play or encode (to & from) without any additional third party software. Supported input source file formats are: - Video format: 3gp/3g2(Nokia,Siemens,Sony,Ericsson) asf, avi (DivX,H263,H263+,H264,XviD,MPEG4,MSmpeg4 etc..), dat, fli, flc, flv (used in Flash), mkv, mpg (Mpeg I,Mpeg II), mov(H263,H263+,H264,MPEG4 etc..), mp4(H263,H263+,H264,MPEG4), ogg, qt, rm, ram, rmvb, str (Play Station), swf (Flash), ts (HDTV), viv, vob, wmv - Audio format: aac, ac3, amr, mmf, mp2, mp3, mp4, mpc, ogg, ra, wav, wma - AviSynth Script Files: avs. Let you specify advanced encoding commands using AviSynth scripts!
