I dunno if that will work. You will definitely need to take them out of the youtube player for that kind of thing to work. Otherwise they will just search the title of the vid, not fill out your thing.
2 ideas though.
Get cpalead gateway. And there is this thing called "Tease Time". Set it to 2 minutes or something. and Put it on the video pages. That way they start the video. Two minutes later the gateway pops up and it is likely to get filled in.
Or if you want to go the whitehat way. Signup to graboid on CJ. 70 cents per free signup. it isnt much but it doesnt piss off your visitors.
