Keith Winstein and Marc Horowitz implemented DeCSS in perl. http://www.cs.cmu.edu/~dst/DeCSS/Gallery/qrpff-fast.pl There is some description of using it here: http://www.cs.cmu.edu/~dst/DeCSS/Gallery/ Does anyone have test vectors for DeCSS. If one had a DVD player and a content scrambled DVD one could use the example they give: % /mnt/dvd/VOB_FILE_NAME | qrpff 153 2 8 105 225 | \ extract_mpeg2 | mpeg2dec - Someone want to extract a few frames from a DVD and include the associated plaintext for testing purposes. I'd like to try reduce the size of the program. Adam
