How to download information about a movie / video

Is there a way to get information about videos you have downloaded from e.g. http://www.onlinetvrecorder.com titled like this:

Frozen_Eiskalter_Abgrund_13.02.16_22-50_pro7_110_TVOON_DE.mpg.avi
Ghost_Dog_Der_Weg_des_Samurai_13.01.28_01-50_ard_110_TVOON_DE.mpg.avi
Copykill_13.01.30_00-50_zdf_110_TVOON_DE.mpg.avi
Der_Blade_Runner_13.02.03_22-25_rtl2_130_TVOON_DE.mpg.avi
Aliens_vs__Predator_II_13.01.31_22-20_vox_105_TVOON_DE.mpg.avi

May be there is a data base you can access and download the information and may be tag the files, the file names.
