Many moons ago AOL put up a bunch of Procter and Gamble soaps for 'legitimate' viewing (that is, P&G brokered a deal). It was very early on (obviously--AOL?!) but they were probably the source of these episodes you mention. Not sure how they managed to make copies, since the technology wasn't what it is today. I do recall AOL was airing stuff from late-1970s and early-1980s, and it was for their subscribers only, of course.
It never ceases to amaze me that P&G is so fickle when it comes to re-purposing their soaps. They go through periods where they release some of the episodes (like this AOL deal), then periods where they refuse to make deals with companies begging for content.
In the late 1980s P&G sold the final five years of Edge of Night and Search for Tomorrow to the USA Network, who aired the episodes in a late-evening slot. Since they aired on 'regular TV' it was very easy to tape the episodes, so those are all over youtube (especially the EON reruns). P&G sold reruns of Another World to SoapNet at one point but SN failed to hold up their end of the deal (which was to air the entire run from 1987 onwards; they stopped around the time of the 1992 episodes), so perhaps that made P&G reluctant to sign any more license deals.
