The national distributor for Sissi is The German Language Video Center
(7625 Pendleton Pike, Indianapolis Ind. 46226, tel. 800 2552 1957). They
tell me they have 700 German titles of all sorts, from 1910 to the 1980's,
mostly without subtitles.  They are in NTSC format, so no special video
player is needed to play them.  For $1 they'll send a catalog.
