ok guyz my problem is...........I would like to download movies but I seem to be doing something wrong

1.chose video

2.chose name,year,producer etc.

3.download for example "*******" it says DVD full movie

but..........It downloads and all that I go to play it and all it is is a trailor for the movie. Is it even possible to actually download a movie from here?Or were my hopes too high.

please help a gurl out.......thnx
