Based on your suggestions i have done the foloowing but the outcome is unfortunately not good
Firstly, i downloaded gold edition of Region CSS Freeand installed hoping the registration may fix the problem but the issue persist. I still get a blank screen followed by termination like mentioned before. So i uninstalled region css free and used the following rippers (to rip video_ts to hard disc) but each one gave its own set of problems:
DVD Decrypter: When i run the start button i get this error
"Media Region Code is mismatched to Logical Unit Region"
DVD Shrink: I get the following error after i select my DVD drive:
Copy Protection Error - The curent DVD's region does not correspond to the region setting of the drive
DVD Fab : I downloaded Gold edition. And unlike others this did not give me any read error but after ripping the video_ts folder for 3.5 Hours the final copy (in my hard disc) was of no use because the video looks garbled (nothing is visible other than some intermittent background).
Clone DVD: I downloaded Gold edition. This doesnt even rip the complete movie. I only see 10KB and 10MB files which are unplayable ofcourse.
