ok me again. been on the hunt and i have came across something that for me worked.
i have tried just about everything i could think of.
the prog is called Pavtube Blu-Ray Ripper and the guide can be found
here.
i tested it out and it worked fine using the method posted above.
here are a couple of sample screens i took from Metallica - 15-08-2006 Seoul South Korea Blu-ray leglessmoof version.
also note the actual screen sizes it saved them at with default settings.. and the small file size in comparison.
screens could be better but i didnt use the pause button on them.
EDIT:: note i couldnt seem to be able to get the main menu to show up but at least screens can be taken
