Hi, i do hope someone is able to help....

I have ripped 2 movies from DVD using DVD shrink, each movie is 2199mb in size and both play back perfectly in PowerDVD (including sound)

When i load either of them into Tmpgenc DVD author it comes up with the video file and the audio format which is correct. but when i go back to edit the file it reflects as no audio. and of course becase these are already VOB files I do not have a seperate audio file,

Any idea what can cause this and what i can do to resolve it, i have tried to play with DVDlab but seem a little confused, DVD author works perfectly other time just this seem to have issues with the sound.

manythanks
