I've mirrored a website using external depth 1.  One of the external pages
linked from the "news" page on my site embeds a video.  HTTrack captured that
page, but not the embedded content.  I'd like to get that content.  Do I need
to increase the external depth, and if so, how can I increase it for the
"news" page without re-mirroring the whole site with more depth?
