IF I want to watch trailers every, EVERY, single DVD or Bluray I own has trailers on them. I can just as easily archive those as I can the main movie.
The reason I use a media server in the first place is so as cut out all that crap and be able to enjoy JUST the movie.
Every piece of software out there that archives owned media has a way to archive said trailers.
There is no reason Youtube is needed to watch trailers.
Since Youtube is not needed to watch trailers if one owns the actual media being archived that leads me to two possible reasons for this trailer push.
One is as I've already stated, caters to people who don't actually own the media dwelling on their media storage devices.
Two is marketing. Both marketing for the X3D, "Our player plays trailers from..." sales job AND marketing from the Google-Youtube side of the equation as it pushes these trailers out to people's media playback devices.
As a feature the time it is taking to implement makes me lean more towards the marketing and pushing stuff from Google side of the thing.
Too bad Mede8er has decided to spend the resources to do this kind of feature but is leaving some other stuff unattended, like sub-titles that do not display correctly.
As for the personal opinions directed towards me, imagine that......
