FAQ.How to know if QuickTime is installed on any target and can play MPEG 4 movies?

Answer: Try this code:
dim q as QTComponentInformationMBS

q=new QTComponentInformationMBS

// "eat " = Movie importers
while q.NextComponentOfType("eat ")
if q.SubType="MP4 " then
MsgBox "found: "+q.Name+ " codec"
end if
Notes: If you find a MP4 movie importing codec you can be sure that a MP4 movie can be opened.
