you want to start embedding your own videos instead, i've had some success with that. that way they will also show up in google search in their own right.
im always careful to write my URL in text onto the video though, and link to it from the youtube description. you never know how clever google are at working out where the video came from. they should give you an option during the upload to state your website explicitly, but they dont.
