How many MOWs have been released on DVD?

I'm looking for official releases of these:

Twin Detectives
The Norliss Tapes
Pray for the Wildcats

THe 1973 TV remake of "Double Indemnity" is included as a bonus on the latest DVD release of the original. The 1976 Irwin Allen produced "Time Travelers" is also a bonus on Volume 2 of "The Time Tunnel."

We've had stand-alone releases as far as I know of these TV-movies (not counting miniseries)

Duel (1971)
21 Hours At Munich (1976)

And I can name some TV movies that were released on cheap Public Domain labels that you could usually find for a few dollars in supermarkets like the above average "Rehearsal For Murder" (1982) and George C. Scott's return to his most famous role "The Last Days Of Patton" (1986).

I'm looking for these on dvd. I have a few on vhs but need to make the swap!

Getting Married 1978
Kid From Left Field 1979
Ghosts of Buxley Hall 1980
Flying High 1978

Brian's Song (1971) was released on DVD, and so were several miniseries like Roots, Centennial, North & South, etc.
