Problem With DVD Conversion

[Graham Todd]

I have a Region 1 DVD with NTSC output.  It was bought mistakenly but I
find that the DVD has not been released in Region 2 (Europe) format with
PAL output, so this is the only version I can get.

I would like to use the information on it for research purposes in an
educational establishment (the University Of Kent), so copyright is not
an issue here (and been checked with members of the School of Law).

What software will most easily be able to convert from Region 1 to
Region 2 and convert NTSC to PAL?  And can any one refer me to a
website to take me through the process of converting?

Thanks to all who can give me some directions.
