MakeMKV not reading playlist accurately (not obfuscation)

Post by tppytel »

(Not an obfuscation problem... I know which playlist I want, but neither MakeMKV nor tsmuxer can follow it correctly.)

I'm trying to rip one of the extras off of the 50th Anniversary Bluray of West Side Story. The extra is a ~20 minute selection of scenes with audio commentary not included in the main title. I've identified the playlist (0300.mpls) and (after decrypting the BD to disk) can view it in BDEdit, where I can see that it includes selections from streams 502-507 along with the entry and exit times for each selection. However, MakeMKV reports a segment map of only 502 and 503 for the 0300 playlist and does not follow the entry/exit times at all - it merely rips a complete copy of those two streams. I tried demuxing with TSMuxer and it fails in a related way - it uses all the streams but it ignores the entry/exit points and extracts a complete copy of each stream each time it enters it, resulting in an 8+ hour video file. But again, the 0300.mpls clearly shows the correct structure in BDEdit and it plays correctly in a hardware player. Also, the main title and one of the other extras on the same disc ripped just fine. So there must be something about this particular mpls file that's confusing these tools. The output from BDInfo follows.

Any ideas or workarounds? Thanks.
