Thank for your response.
In fact, I stopped MKV right after posting my message.
On checking the small files, I found they related to some interactive features necessitating access to Disc 2.

Something strange here:
I did not come across any error but Make MKV has identified 1 large file (23 gb) and another 430 files approximately with an average size of 780MB each. The estimated time is 18 hours (still running as I write this). Has anyone else experienced such a phenomenon?

Many thanks Woodstock. Apologies, I should have read the solutions for ripping errors
However, I ran MKV as administrator and it worked without problems.

Epilogue

I resurrected my old laptop running win 8.1
No problems at all. The disk was ripped as expected with no problems!

Apparently, after a recent Win10 update there are problems with some external drives. I will have to sort that one out.

Thanks to all for your help.

Thanks Grauhaar, but I'm not any the wiser.
Do you think it is a Windows issue?

Many thanks Grauhaar.
I do hope Mike looks at this issue.

Yes, other discs are fine. This one appears to be heavily protected and issued in the UK.

After enabling the debug log I tried to rip the DVD and got the following error messages: MakeMKV v1.15.0 win(x64-release) started Debug logging enabled, log will be saved as C:\Users\joe/MakeMKV_log.txt DEBUG: Code 100860416 at )71vN$q_,zgve5)N6K:213131778 DEBUG: Code 100860416 at )71vN$q_,zgve5)N6...

Many thanks.

I have used the Blu Ray drive with MKV see below: 'BD-ROM MATSHITA BD-CMB UJ-120 1.01'
The same drive works fine for other DVDs.
I will repeat the process and send you the log.
Best regards

Many thanks for your response. The DVD is pristine in its cleanliness as it is new out of the box. Nevertheless, I have have air-cleaned it with the soft brush of the hand pump that I use for film negatives. You have helpfully suggested that there might be a hub crack, I have minutely examined the d...

Hi, I'm trying to rip a DVD (brand new). Having reived the error messages below I have run MKV as administrator but the MKV icon remains greyed out. OS: Win 10. Hope you can help.

Thank you for your advice. My apologies for this delayed acknowledgement. Moribus, I did what you suggested and successfully created an .mka file for each chapter. :D Many thanks. The difficulty is that the audio (the BluRay is a musical) ending at each chapter is brutally cut on the fade out. :( An...

Many thanks.
I used the open/save as MKV method.

I installed mkvtoolnix but from the gui cannot fins a way to extract separate tracks. I get the entire soundtrack as a .mka file.

The help file of the mkvtoolnix application shows the need for scripts.
Am I doing something incorrect?

Am a newbie, so please bear with me. As I write this, I am using MakeMKV to back up my BluRay disc. I have checked only the biggest video file (38gb) and the English audio. (Have excluded subtitles and other languages) How do I go about 1) extracting the audio, then 2) splitting the soundtrack into ...
