I guess you could set them up like episodes within a season and then they would be listed and you could select each or the watch all option.

Nick, there are 2 requests here and I'm sorry if that has confused things:
1. The ability to have a library of movie trailers (normally ones for movies 'coming soon') to watch as entertainment on their own. What you suggest would work for this. Ideally there would be a choice to either download or simply put a URL in the library and stream.
2. What preproman was asking for was my other request, that there be an option on the movie detail screen, along with the poster and movie details, to 'play trailer' and for this to play the trailer for that movie - useful when you have a few people round and are deciding what to watch. Again, ideally you have a choice whether the trailer is locally downloaded, like posters, when the movie is added to the library or whether you rely on a web link. There should also be a choice of quality - SD, 480p, 720p, 1080p.
Personally, in MeediOS, my 'coming soon' library contains URLs to 480p trailers - I am prepared to accept, like YouTube, it may not always be reliable - but the trailers for my own movies are all downloaded in 720p. The additional space for a trailer is nothing on top of 40GB for a bluray!
There is a third request from some to be able to automatically choose to play some trailers from the trailer library before a movie, like at the cinema. I can see that might be nice for some, but personally that doesn't interest me.
