Hi can anyone tell me how to update a Samsung DVD 250GB Hard drive model DVD - SH855M. I have had it over 3 years and it has stopped playing some DivX movies, or stops playing movies before the end, which are ok on the laptop. I have been told you can update the DivX code or something similar. I have been advised to go to some website and download an update for the divX code but I haven`t a clue where to start or what to do. Any advice would be appreciated for a non techie person like me, Thanks
