Sherlock, I believe we've stated multiple times that the issue is NOT the episodes that aren't available for purchase. My last post was meant for those who said that they HAD to get illegal copies of the Time-Life episodes, as though it were a life-and-death situation.
And yes, if it comes to that, even tape trading ain't exactly the most legal thing in the world. I adore my tape collection, but if Henson demands that no more tape trading go on, I would respect their decision. Hopefully, instead, they'll start releasing more of their library on video and DVD, and I can dutifully replace my copies with store-bought ones.
We complain that there isn't more Muppet merchandise out there, and then we do everything we can to avoid supporting the Henson company financially. I just don't get it.
