Many thanks for your replies! All are much much appreciated
As it turned out Olyteddy had the right hunch A friend a little more knowledgeable than me told me exactly the same. Burning it with DVD Fab Decrypter was a snap; size was about 7.5 gigs.
What is the audio component of the movie? If LPCM (uncompressed) then that could account for it. Otherwise you really need to ask where it came from. IIRC screenshots in PowerDVD are on the right-click menu...

There are some titles that have bogus tables of content and or IFOs that make it appear that they are a lot bigger than they are. A good ripper should be able to sort it out and allow you to copy the movie only.
That movie is under 8.5gb and fits nicely on a DVD9 aka DVDÂ±R DL! Rip with Ripit4me & DVDDecrypter.
