how to convert DVD/Video to iPod?

I have a huge collection of DVD movies and video files. And I always put a few movies on my iPod to kill time while travelling.
DVD movies cannot be transferred to iPod via iTunes, so I had to find a converter to do that. I have used a few converters and the one I am using now is Popular softwares online . It is not free, but not expensive either. I decided to spend the money coz it does a good job on the final quality and conversion speed. And if I don't want to put a whole movie, I can just convert part of a movie onto my iPod with this app.
Most of my video files are not MP4 formats that can be directly used on iPod, so I also bought the Popular softwares online from the same company coz I thought it would also be nice app, and it turned out to be so Actually, this video converter and the DVD converter are pretty much the same as far as the functions and the operational steps are concerned, and the only difference to me is that one is to convert DVDs and the other is to convert video files. If you also want a video to iPod converter, you can just download a trial version to see if it is what you need.

i use total video converter to convert any video and audio file i need.
it is easy to use and it can convert files to any files you want in less than a minute.

I use a program called Handbrake, works alright for me. I can't see why apple doesn't just allow you to put already owned DVD's on ipod anyway.

nice try, thanks!
