name='Carl V']It is annoying, but sadly this has always happened with DVD's. I still have some of the early discs of various Hollywood releases and some of them include nothing more than a trailer and they were still charging 20 quid for them, as much as a 2-disc feature-packed release - even from the same DVD producer (in this case Paramount).
I get equally annoyed when a film is released on DVD with nothing else, and then a year or two later the same film is re-released with masses of extras, documentaries, behind-the-scenes information, etc.
If say, a 1960s film gets released on DVD for a second time with a wealth of extras, you'd have to wonder why they weren't included in the original release bearing in mind that, with the age of the film, the extras would have been available to begin with. I guess it's an attempt to get people to buy the same title twice, which I certainly won't do.
