Next Tech takes 2 an half hours to read and backup my 1998 movie

Newest next tech and new sata asus burners(I replaced samsungs because I thought they were problem) takes over 2 hrs. to read 7 burn my movies.Even ones bought in 1998.I purchased Cloner 8 an it does the whole back-up in 30 to 40 minutes.Any body have this problem?

Depends on the data per dvd. I never had this issue except running an xp machine personally though. When was the last time you gave your PC a good cleaning and defragging?
