How can they show trailers to movies that didn't even hit the theatres yet? The only way to see that is during commercial breaks to popular shows or in the movie theatres themselves.
YES!! There are THREE half-hour shows that show nothing but trailers in glorious HD. THE ULTIMATE TRAILER SHOW is the best one, hosted by Robert Wilonsky (who'll also share his opinions on them). The other two are TRAILERAMA and NOTHING BUT TRAILERS, All three shows are on HD Net (Ch 569).
