Thanks for sharing. But I am a noob with this muxing stuff so I was hoping for an easily modifiable MKV to add German dubbing and subtitles to the silver screen edition. So I am not sure this iso will help me reach that goal. Or can I make an GOUT synced MKV out of it?
If you extract the contents from the iso file (winrar will do it), and demux the 0000.m2ts file (tsmuxer will do it) from the STREAM folder you will end up with the already synced video stream.
All you have to do is remux it back again with the audios and subtitles you want, also, tsmuxer will do it.
Maybe you will need MKVMerge to end up with a Matroska container since tsmuxer can mux only BD, M2TS and TS.
