2 questions about trailers

I'm using Win7 64 bit and XBMC (whatever the last stable release was) with little to now issues, which means I need something to mess with.

1) What's the best way to get trailers for existing movies on my server? I'd also like to know the naming scheme that they should be saved with, and what skins support viewing them via the library (I'm using the Big Alaska mod at the moment).

2) What's the best way to download trailers for new movies? I'd prefer to be able to pick the quality, but I have to be able to download them as my ISP is incredibly slow.

I personally download hd 480p quicktime trailers from the quicktime site most average 40 - 50MB in size and are great quality, its very easy now they have changed the format you just right click the link and use save as to download

You label them

moviename-trailer.mov

or

movie-trailer.mov (if your movies are in separate folders)

Two more sites, download them the same way

You can aslo just use trailer URLs but if your connection is slow your probably better off downloading them plus they never disappear
