"these are daily videos and there's no archive to speak of"

You mean the older videos are no longer on You-Tube?

I don't watch them myself. Not enough time to go downloading them.

So, Luke? Care to chime in on this question? Are all your previous videos online still? Or do you delete them so there's only the most recent?

Hmmm....a question of concern arises, can old videos be replaced?
