The films listed below have German audio tracks.
The majority of the films listed below are found at amazon.de,
and a few are at amazon.com. Both are very reliable in
their customer service and I've heard no complaints about
their products. Many of the older films can only be found
in VHS format. Most of the newer ones are normally issued
as DVD's. As far as DVD's are concerned, most American-made
films already have built-in language options, but I've
not seen many that provide German. More frequently they
are Spanish &/or French, due to the proximity to Canada
and Mexico, I guess. Another factor to consider is the
"regional encoding." However, most quality DVD
players are able to play German DVD's.
