I'll preface my remarks by stating that I am not a Web Page Developer.
As long as the .mov file is embedded in your document, it should be
displayed properly regardless of the "Local Machine Lockdown" settings.

That's correct. And it has been the default setting since the release of
SP2, the vast majority of IE7 users would not have "Local Machine Lockdown"
disabled by having placed the checkmark in "Allow active content to run in
files on My Computer". Usually, only those who do not(for what ever reason)
want to add the "Mark of the Web" to their local .html files(to allow active
content to run on the local machine) would need to disable "Local Machine
Lockdown".

The problem with IE7(and it's new Cross Domain Protection feature) only
arises when you try to link directly to files on the web such as, .mov,
..mpeg, .swf, .wrl,...etc. in the form of www.someserver.com/some.mpeg or
"some.swf", "some.mov"...etc. As you found out trying to link to your .mpeg
file directly with Local Machine Lockdown disabled.

IE7 comes Opted in to this new security feature by default, and there is
mechanism in the UI to Opt IE7 out of this feature, it can only be done via
the Registry Tweak described at the MS Knowledge Base link I supplied. As
long as your media files are embedded in the document, there is no conflict
between Local Machine Lockdown(regardless of setting) and the new IE7
security feature(Cross Domain Protection). The conflict only arises when
you try to link directly to the Media file as described above, then you must
either enable Local Machine Lockdown, or Opt IE7 out of the new security
feature using the Registry Tweak in order to get the file to display in the
Browser.

Sorry this is so long winded:)

Good luck,

Donald Anadell
