Yes, I know about BeSweet. But sometimes powerful programs can't do very simple operations..... no, they can but do it very slowly because optimized on other work. So BeSweet is optimized on processing audio and implement delay not by delaying but through processing entire audio.
Such as PGCdemux creates celltimes.txt by processing entire PGC (try create celltimes without audio & video demuxing in PGCdemux and in IFOedit).
