The problem just seems to be more and more people are not buying things on disc anymore.
And even fewer people are buying TV shows on Blu-Ray, for the most part. There's still a healthy (though shrinking) market for TV shows on DVD out there, but Blu-Ray is a harder sell.
This is too bad, really. I'm glad we have The Prisoner, The Twilight Zone, Star Trek, and Star Trek: The Next Generation on Blu-Ray, though.
