The title says it all -- I made a complete 1:1 copy of a dual-layer BD (Breaking Bad, Season 5 Disc 1 FWIW) using the 25GB BD-R preset compression settings for the output ISO. After burning the ISO, the resulting disc exhibits minor but noticeable lip-sync errors on playback (i.e. the video and audio aren't synchronized). I tried creating the ISO both with and without the "audio core only" box checked and played the disc back on multiple players -- in all cases the lip-sync errors persist. Am I missing anything or is this a known bug?
