Hi,

I tried changing the Vob. extension to mpg. It works but it is not editable in Premiere pro 7. Then I used Sound forge and converted vob into avi. It was then editable but the sound and video were out of sync badly. Then I tried wift iSofter, a DVD ripper. Converted it into avi. format again. It is editable in Premiere and seems to be fine although there is a slight loss of quality.
