cUrl and Images+Video

[tempster09]

I am practicing php with a local server running and I created a class that uses curl to open pages, fetch the html, put it into a DOMDocument, parse it, etc...I began following links and downloading images and checking their mime types so I know how to handle it.  There isn't really much information about doing it with video files though like mpeg, mov, etc...When I try simply following the link and downloading it locally it works, but I get no mime type, or a wierd mime type that doesn't make sense and it will only store a blank file (but it all downloads ok) I just can't play it.  Anybody know anything about doing video stuff with php?
