Following-up to myself:
The dialog header in question simply represents the supported default Open
With selection for the current file set. If you select more files than the
handler in question's implementation *type* is perceived to be able handle
correctly, it'll drop out of the context menu / open with selection list,
and thus that default moves on to whatever remaining implementation types
that do support handling as many files are you are trying to open.
Single verb handlers with no drop target support will support few files.
Single verb handlers with drop target support will support a larger number
Full shell extension / context menu handlers will be able to support a much
larger selection of files.
This applies to applications generically. I don't know what specific
scenario you're trying with QuickTime (what file type?) but it sounds like
they're implementing an older style of verb / context menu handler.
is a good starting point for understanding shell associations.
Speaking for myself only.
