I think I taped every episode that aired where I was, though I do know I had to eventually get a copy of one of them from a friend, probably because my first copy somehow got taped over, though it's possible I simply forgot to tape that one. There were of course some that didn't air in the US, and at least one that was scheduled to air but got preempted by one of Ross Perot's presidential campaign infomercials.
The one I got from a friend is really lousy because of some tracking issue, and of course none of these home recordings on VHS from ~20 years ago look all that great. Worse, I no longer have the pilot, "Young Indiana Jones and the Curse of the Jackal" - shortly after it aired, I mailed my copy to a friend I wanted to see it, simply assuming that I'd be able to record another copy sometime (or better yet, buy a high-quality commercial version when the series made its eventual home video debut). If only I'd known...
But that said, I do have most of the series in the form of homemade tapes of varying quality.
