Using SmartRipper-> DVDx to convert Dusk Till Dawn. The output is three mpg2 files. The second and third file have perfect audio.

The first file is good for the first 11:20. This corresponds to the end of the opening credits. Here the audio suddenly lags by more than a second. It stays behind for the remainder of the file.

I re-encoded it making sure that everything else is turned off, and it makes the same jump. Any experience with this kind of problem?
