It's incredibly simple; it has to be or I couldn't do it :;g::

I only have a trial version of this one which lets me rip ten mins at a time; which is plenty for vids where you only need a few seonds or so for each bit.

It's worked great for me; you put the DVD in, load it, select the 'clip' option and input the exact bit of the DVD you want to copy. Warning; what Real Player etc say is the time doesn't always match up exactly so you need to allow for that.

Then I import it into Windows Movie Maker which comes free with Windows and cut it to exactly what I want, save it, load it into YSI or similar and post the link.
