Rule of thumb. If something's on youtube for more than 10 minutes, there's no issue. Youtube clamps down hard on fast on stuff folks don't want on there (Witness how fast new unauthorized Trailers come down). Lots and Lots of Doctor Who available on YouTube, yet, when missing episodes were found, they weren't there, and the Reconstructions were also pulled for the still missing episodes of those Serials, so, the missing episode Sales wouldn't be affected.Legally?
