DVD to iPod
Mobile Deviant Community – How To: Put DVDs onto Your PSP. OK, this for a PSP, but you use much the same process to get a DVD into iPod format since both the Sony PSP and the Apple iPod use h.264. The basic idea is you use DVD Decryptor in no file break mode so that you get a complete .VOB file. This has MPEG-2 video and PCM audio.
On a PC, you then use VIdeola to convert the MPEG-2 to H.264. Only tricky part is that if you have anamorphic video then you need to use the profile which is 320×178 rather than 320×240 pixels.
