Ok... Just to be clear: I'm not a JRiver employee, I'm just another user, and I'm trying to help you for basically no reason other than to be nice. So I'm not obligated to be here, and I'm trying not to lose my patience. So please, if you want help, read this post carefully.
You've said you answered the questions. But you have not answered all of them. One you have repeatedly ignored.
Read this quote. I have asked you twice:
What do you mean you get "the film without the commentary"?
Do you mean it plays with the main audio track, instead of the commentary track you want? Or do you mean the video plays with no audio at all?
I am asking for the third and last time. I need an answer to this question. It matters.
You have said "all I get is the film without the commentary" and "However the two versions with commentary do not play the commentary audio track". You've also said "same problem". Those are not answers to my question.
I know the audio commentary does not play. You said that at the beginning, and I am paying attention to what you say. So what I am asking is
Do you hear SILENCE, or do you hear the REGULAR AUDIO TRACK? Do you understand the difference? They indicate different problems.
You said you can't do screenshots because MC crashes when you try and play the DVD. If MC doesn't crash when you DON'T try to play the DVD, then you CAN take the screenshots I asked for. I thought you would get that. Or did you really mean that MC crashes immediately every time you try and run MC? That's not what you said, but that would prevent you from doing screenshots. It would also prevent you trying this next step:
With regard to your crashing, if MC works normally when doing things OTHER than playing your Citizen Kane video, meaning if you just start MC by clicking its icon then MC runs and you get the interface and it doesn't crash, then take those screenshots (there's nothing stopping you), and they let's try to fix the problem that it crashes when playing Citizen Kane (the ripped file, not from the DVD-Drive) by deleting the contents of the following two tags from the Citizen Kane movie:
Bookmark
Playback Info
Then try playing it again, and hopefully it will play. If you don't know how to delete the contents of those tags, read this:
https://wiki.jriver.com/index.php/Edit_Properties_with_the_Action_WindowIf clearing those tags allows the movie to play again (without the commentary, because that problem isn't fixed yet) then also take a screenshot of the right click menu you get when the movie is playing. Play the movie, right click on it, the menu will pop up, and immediately hit Alt-PrintScr and that should get the menu contents into your clipboard. It will be helpful to see that menu.
If on the other hand MC crashes immediately every time you run MC, you probably have a corrupted library or registry. Try rebooting the PC. If that doesn't fix the crashing, one of the developers might be able to comment on the best next step in that case.
As for the problem of crashing when playing from the drive, you said rebooting doesn't help. I will leave that particular problem for the JRiver developers. They might want a log file. If you do a google search for "jriver dvd play crash" you will see several other threads that give you tips to try. Many of the threads refer to Windows DVD playback being broken by Windows updates, which are then fixed by more Windows updates. If you want to pursue your broken dvd drive playback before responding on anything else, that's fine. Good luck.
As for what I mean by "rip properly": there are a lot of things that can go wrong or be done wrong during a rip. I do not know if the ripped file actually has all the contents you think it has, and without the full file, I can't be sure there's nothing wrong with it. Additionally, there can be problems with playback of IFO images, as you saw in the other thread. The only real reason to have the IFO is to maintain the use of the interactive graphical DVD menu. Some people love that and think it's really important. Personally, I think it's a toy, and gets in the way. If you don't feel you can't live without the menus, MakeMKV is a program that does an outstanding job of ripping a disk losslessly, preserving all desired soundtracks and subtitle tracks from the movie, and puts it all in one file that is highly compatible with many playback applications, without forced trailers and advertisements, FBI warnings, or other nonsense. You almost certainly would not be having this problem if you ripped the disk to an MKV. It is also easy to validate the integrity of an MKV file using mkvalidator. So in my opinion, ripping to MKV is preferable in most cases.
So we're trying to fix your problems with this rip, but you also have the option to rip to a different format and avoid these types of problems.
Hopefully this is all clear, and will get us back on the right track.
