I wonder what's going on with your files compared to mine. I didn't have to do anything with MKVToolNix or Handbrake to get mine to play. Glad you got them working.

@eromin did you actually check the 'playability' of the .mkv files created? and if so, in what player? Yes, I did test playability of all titles from S1 D1. They played with VLC on both my Windows 7 (VLC 3.0.3) and macOS 10.12.6 (VLC 2.2.6) machines with no issues. I've also tested them in Plex Med...

Version 1.14.2 was just released, and it seems to have fixed the issue. I just tried Season 1 Disc 1, and all extras ripped without errors. I don't have time to do the other discs at the moment, but I wanted to give everyone following this thread an update.

Yes great work, helpful forum but alas, same issue -- no extras ripping successfully on S1-2 :( For devoted fans of this TV franchise the extras are pretty much the main reason we bought the Blurays, well that and the DTS-HD MA. The video quality is good, but little better than the Amazon version. ...

Just saw that 1.14.1 was released today, so I tried the problem discs again. No change. The first 2 extras on Season 2 Disc 2 rip, but none of the other extras do. I'll email my logs for all 4 discs where I try to rip extras only.

Thanks for your work on this! It's much appreciated.

mike admin, Thanks for checking in on this thread! I just tried all of the affected discs with 1.14.0, and unfortunately that did not completely fix the issue. The good news is that 2 of the extras on the Season 2 discs appear to be ripping now, though I've noticed some frame drops during playback o...

Update now that I've finished ripping all 6 seasons: Only Seasons 1 & 2 have issues with the extras. The extras for Seasons 3-6 all rip and playback without problems.

Are you having MakeMKV convert audio as you rip? I rip LPCM audio BDs regularly, but I have MakeMKV leave the audio tracks as-is. Most Sentai titles are LPCM. I'm not sure if this was directed at my comment, or crboc's, but I do not have MakeMKV convert any audio as it rips. I want the bit-perfect ...

I am having the same issue with the extras on Seasons 1 and 2 of the Community BDs. As 4@ron= says, the episodes are fine, but it runs into an issue once it gets to the extras. MakeMKV throws a seemingly endless stream of DBG ASSERT: Le;bTF5]e*?;""b$^~H;'*T%qV? at :diPhrdUKS`qxZu+hkA(:1212...

I just tried ripping the same Blu-ray (Simpsons Season 15) and encountered the same "no FUTs" error, which caused 7 of the 8 titles I attempted to rip from disc 1 to fail. I can confirm that reverting to 1.8.13 gets around this issue, and I have successfully ripped discs 1 & 2 so far. ...
