Looking at the listed size of the last *.vob file, it looks more like the PAL version to me but the size does not exactly match my (original) copy!!

I'm not sure how you tell from the size of a VOB file whether it's NTSC or PAL! Both were encoded to make the most of the disc space, so if it doesn't match the PAL disc I guess it must be NTSC - I don't have my ISOs here to compare. Then again, it could be down to rounding errors or what size kilobytes and megabytes are today.

If Wesyeed had uploaded the JPEG we'd know from its filename
