This is the second time that PC accessibility has enabled content piracy. Pirating music from CDs using MP3 is easy for just about anybody.  However, in the case of DVD’s there are several reason why DeCSS may or may not be a large concern:  

¬       CSS was merely a temporary solution:  Rumors among the entertainment industry state that, despite rumors of panic among Hollywood studios,   CSS was never intended to be a serious deterrent to piracy, but only to prevent “casualcopying”.

¬       The Recordable DVD:  Right now, recordable DVD drives can only store 2.6GB per side, and DVD movies are either 4.7GB or 9.4GB. People copying movies with DeCSS are turning their DVDs into low-quality VCD. Even Jon Johansen, who was involved in the development of DeCSS, can't understand why people bother.

In addition, these discs still cost more than retail  movie titles and lack compatibility with many players.

       But many predict that high-capacity, affordable   recordable DVD is coming. In the near future it is predicted that there will be there will be 4.7GB recordable DVD drives, and DVD copying will be much easier. These predictors suppose that it may not be a bad idea to hold off on releasing the drives until the copy protection issue is sorted out.

¬       Loss of Full Functionality:  The decrypted DVD consists of .VOB files (aoubt 1GB each)  since each movie comprises several such files, there is a loss of navigational controls and interactive features when copied. 

¬       Incompatibility with Operating Systems:  There are reports that DeCSS does not work with either Office 2000 or Windows NT4 systems.

¬       Piracy:   If many people do choose to utilize this still expensive system of copying and resell the degraded contents, it is possible that this might have a serious effect on the entertainment industry.  This issue is dealt with separately in the section The Effects Of Piracy.
