whitcombe pass, TV doco

does anyone have a copy of the series "Explorers" from peter elliot?
I wanted a personal copy on DVD and i asked TVNZ and they told me they cant release it on DVD due to a copyright issue, yet people probably have recorded it from the TV, if it has screened on heartland again, that would be great if someone has recorded it in HD, of course i dont see any problem having a personal copy if its not sold for profit, as its only for personal use.
How else am i supposed to get hold of it?
