Thank you for the reply.
Actually Scenarist is making me indecision too. because I will need to spend much more time to learn it comparing the other sofwares. but at the same time I am talking about a professional work which I have to make it as industrial standards!

yes.. using dvd lab pro is easier for me. but I am worried about quality of the picture after demuxing? I am getting the .vob files from a released dvd directly into dvd lab pro. do you think the quality of the files effecting from this move?

and is there any standard points that I should make on the master?

some people told me that making the authoring works with dvdlab pro may cause the dvds not working on some players. have you ever made a replication dvd master with this program?

another question: which authoring software is the best alternative for Scenarist SD on dvd ‘replication’? is it dvd lab pro? or which..
