Hi. Right away since the first second. The Adele concert piano playing I posted happens within the first 30 seconds more or less. Mkv files.Are your BD folders 1:1 rip from the original disc? If so, can you list a few (well-known and popular) titles with the issue? Preferably UHD bluray, as I’m more likely to have them, bluray otherwise.
Are they out of sync right away or after a while? I played a couple of DTS-HD blurays and didn’t notice any sync issue, but I only played a few minutes of each.
