Do they play okay? I've had some mixed, albeit limited, experiences with unofficial releases.
They play fine for the most part (these are mostly FX reruns of it)-- the site I got this from did state quite clearly in their TOS that there would be some problems w/this and other old shows they purvey there (so in essence, I did assume some risk of having these troubles).
The troubles I've had (fortunately quite limited so far) have included large images blocking the action (on one 1980 episode and one 1985 episode), and one 1983 show coming up short and not finishing with end titles; albeit I assumed these risks, I would still purchase from that place again, because personally, that is the lesser of two evils (better, in other words, and IMO, to assume the risk of defects with bootlegs of an older, yet also IMO, quite good, show, than to purchase functioning DVDs of a more modern show that I'm not sure I would have really enjoyed [
Trapper John, M.D., while it does have some romantic, love and relationship content with its medical drama, does not seem to have as much of it as that more modern show
Grey's Anatomy, which I've never touched, and never will; also, this was very low-priced at only $62, taxes and shipping included, whereas if I had gotten any of
Grey's Anatomy, I would have spent so much more, as much of it as is on DVD [and also, Pernell Roberts was one of the best actors Tinseltown ever had, and was/is far better here in the title role than Katherine Heigl and Ellen Pompeo would have been for me on
Grey's Anatomy]).
