Where can I find copies of old made for TV movies... such as Disney's
"The Bermuda Triangle" and "Kit Carson and the Mountain Men" (Not 100%
positive on the second title, but it incluces mountain men) for sale?

Go look up these titles on www.imdb.com. For example, type The Bermuda
Triangle into the search field. Depending on how unique that title is,
you may go direct to a page dedicated to that movie, or you may get
several links to titles which are near matches. But one of them may be
the one you're looking for.

   But once you click on a title, you'll go to a page filled with data
on just that movie. In the upper-right corner of the page will be a
little box indicating if the movie is known to be available on either
VHS or DVD. If it is, then click on the little icon and it'll take you
to a vendor who's selling it.

To find most made-for-tv movies, look on this site:

http://dir.yahoo.com/Entertainment/Television_Shows/Made_for_TV_Movies/

There are 4 pages of made-for-tv movies, so I think it should cover
all the movies you want to find.

Yes, imdb contains info about them but neither of the two I was
wondering about show they are available.  Surely there is some way to
get copies of old movies such as these.  The 4 pages of made-for-tv
movies didn't contain either of the main movies I'm looking for.  The
Bermuda Triangle one that I am looking for is the 1996 one with Sam
Behrens.
