I thought that you might not have setup AnyDVD to remove the â€œAdverts and Trailers".
I am sorry but I donâ€™t use DVD Shrink because it is â€œDeadâ€ software, which is not supported and hasnâ€™t been updated in a year. So I am unaware of the workings of DVD Shrink and canâ€™t help you out.
I would suggest using the AnyDVD-CloneDVD, which has excellent support and being updated routinely.
I know that the AnyDVD-CloneDVD combination will work for what you are attempting to do.
