[GEM-dev] Gem says quicktime ok, then disagrees with itself

[chris clepper]

A DV stream is not a Quicktime file, it's the raw data with no 
container at all.  It is possible to have one of the DV formats (DV25, 
DVCPRO, DVCPRO-HD) in a Quicktime container, but that is a different 
file type altogether.

Quicktime API can handle .dv file streams on OSX and Windows.
