:thanks: Great answer! I've never seen this explained quite so well before! And for working on this particular Sunday--best wishes for the new year to you jdobbs!!!

Neither has my SONY although my NAD is highly finicky about audio buffer runout. mpucoder has posted a forumula about this - see Regards

Ahhh! That's the thread. I remembered posting about this in a thread with mpucoder. It was frustrating to successfully demux before josoto's PGCdemux for the reasons mpucoder cited regarding reading across VOBID boundaries for the complete audio data.

Has something changed recently with Layer Break removal (i.e., under the standard setting)? I've been seeing a lot of layer breaks during playback of my DVD-RB backups lately... Wait... I haven't been running some of my output through Shrink lately -- that's probably it. I'll try that aggressive flag if it does the same thing...

just to add another 2 cents I DO have a SONY player which VERY occasionally choked on layer breaks that had been forcibly removed by shrink or RB (agressive mode) the sure-fire solution I found was, IF the LB was left in the output of RB (used in the default non-agressive mode) and I still wanted to remove it: use the excellent pgcdemux to demux the audio, video, subtitles use the excellent muxman to reassemble/rebuild the DVD (subtitle colour palette will also have to be copied back from the original) alternatively, of course, you could pgcdemux, muxman the original source files BEFORE using RB (but you won't get help from jdobbs if you preprocess anything and there's a problem!)

It gets complicated when the video/audio just isn't meant to be a seamless joint.
