I am working on a DVD project that involves 25 plus DVDs with multiple clips on each DVD featuring interviews with members of Upperchurch GAA club.
Converting VOB files to work with Adobe Premier Pro CS3 can be straight forward or a nightmare. You can rename the extension to mpg and it may solve the issue. Sometimes however you do need to convert the format.
The latest version of mediaocoder are refusing to do this for me, undoubtly I am making some simple mistakes, but having spent several hours trying to fix it I have given up.
VLCplayer an open source media player has nice simple intuitive save/convert interface which seems to do the job.
