you know, first of all, we need a useful tool. so you need a powerfull and professional ripper for our need.

there are so many kinds of video format, mp4, avi, mov, aac, wmv etc. which one is you want to rip to? of course it depends on where do you want to play the video in. here are something i can remeber about what format can be supported in different players.

PSP: mp4(mostly 320×240), avc/H.264(higher quality than mp4), mp3, aac, wav etc

iPod/ Apple TV/iPhone: mp4, m4v, mp3 etc

zune: wmv, mp4, mp3, m4a, wav etc.

window media player/ movie maker: avi, wmv, MPEG1,mp2, mp3, wav etc.

and most MP4 can only support mp4 format;

some cell phones can play 3GP videos.

that is all i can remember about them. although iPod and PSP can both play mp4, they are not same. cause there are many kinds of mp4 you know. so we need a really professional ripper for your iPod or PSP. i got a PSP 2000 so i always use this Leawo FREE DVD to PSP Converter.
