How to import Dvd instruction media into my ipod?
I have some instructional DVDs on pshop, my camera & using various software that i would like to import for viewing on my ipod.
I believe most of these are in a quicktime format but will have to check on each one.

Is there an easy way to do this or do I need special software?

I think I posted this in the wrong section before I saw this section.
sorry.

I think you will need to convert them to mp4 then sync onto ipod.
