I track the same with my viewing history of the boys, minus Laserdiscs (which I never owned). Although I've watched the boxed set DVDs multiple times since it's release.My history for these films:
I saw each on tv growing up 3-4 times each.
I collected them all on VHS and Laserdisc and watched them all 3-4 times each.
I collected the flipper sets on DVD and watched them all twice
I collected the box set on DVD and watched them all once.
I was getting ready to watch them all again so now I can wait for a blu ray treat.
