Trailer Audio?

[Tryptic]

I'm not sure if I'm even allowed to ask this. I just came up with an idea I'm really excited to try working with, but there's a couple trailers that I would like audio from, that I feel will really fill it out a bit. One of them is an anime, 3 of them are non-anime.
My first question is, is there a legitimate way to get old movie trailers, without having to buy a disc on which the trailer might possibly be found? (I guess, technically, I'm asking if DLing trailers is acceptable... since they're really advertisements, are they still copyright? But I don't know if maybe there's a third alternative I hadn't thought of, like buying it on iTunes or something?) If even asking about the legitimacy of this route is out of line, then I apologize in advance, but if I'm going to have to buy a bunch of movies in the hopes they have the trailer I'll need, I need to know now, because that's just not possible for me.

The second question (if the answer to the first is "yes") is... Can you pull the voice track from the background tracks in a trailer? I know you can with SOME CD's, but are trailers just smushed into one audio layer.

And the third question, whatever the answer to the first two... How much work is it to either dub my own audio for a trailer, or find someone who might be willing to do it for me? And is payment usually considered appropriate if I ask someone else?

Sorry for the multiple questions at once, but these are all things I'd like hammered out before I begin finalizing my audio tracks.

Thank you. And as I said, if any of this is out of line, I apologize in advance.

1.) Sometimes, the movie's official website has the trailers up for download.
2.) No. The only way that would be possible was if there were multiple audio tracks available, i.e. surround sound, where then it is not even guaranteed that the voice will be isolated on it's own track.
3.) Just ask your friends to do dubbing for you. As far as recreating the trailer audio, the film's soundtrack usually has the music featured in the trailer somewhere, and you can get free sound effects all over the internet.

For many of the most recent (last 6 months or so) trailers, you can download them directly from the Quicktime trailer site - the link is a tad obfuscated, but it's really easy to figure out if you've seen any of the filenames from saved copies - right-click on one of the buttons on the movie's page, copy the link address (not the image address) for the particular size you want, in my case I always try to get the 1080p version if available, paste it in the address bar, and stick a lower-case h right before the 1080p in the filename. Then hit enter.

It's soooo much easier to do this since Apple reorganized the trailer site. Before it required more digging around in the site's actual source HTML (which is still the way required to get the Mac/PC TV Ads).

Many of the trailers on there have 5.1 channel audio, although whether the voices are on separate channels from the rest of the audio I don't know. I've never cared enough to check.

Not very often will you see a voice track isolated on any downloadable media like a trailer, surround sound or otherwise. The voice will almost always be mixed with some background music or sound effects in that channel.

It's certainly possible...

I am at this dellema myself. I would like to use lines spoken by the actors on my DVD, but I have a problem with the background music from the show bleeding through against the main audio track. (Beta testers know what I'm talking about). I have yet to find a solution for this problem.

Is it even possible to seperate or filter voices/vocals from background audio ripped from a DVD?
