I have PC using Sony 12. I have been successfully copying DVD .VOB files to the hard drive, then I change extension to .mpg and I can play with sound. however, when copying another .VOB file, intermittently I will lose the sound track using the same steps as before. I am copying from a long video so there is sound all thru the video. when I import a another DVD it can again have the sound. is there some setting that will make it work consistently
thanks
