Hi Najum,
Unfortunately, from a copyrighted DVD, you’re likely to run into a ton of issues. If by any chance the version you have is not copyrighted, you could try to use the original VOB files and drag those into Premiere, if you get an error, try renaming those VOB to Mpeg. Ripping from VLC is most likely the issue and I would recommend a more professional application, but these will not work with copyrighted content.
