Clips/Trailers for icons

I'm wondering where you guys get the clips/trailers/whatever you use for your mini-movie icons. I've found a couple, but I can't download them from apple trailers. Also, the ones I do find are .wmv, and Virtual Dub doesn't support that - anyone know of a way to convert them so they work? I've tried renaming, and it didn't work.



That's one of my first movie icons, does anyone know how I can get it down to 40KB or less so I can use it as a LJ icon?
