Copy protection and audio not matching scene

Post by nmbugs » Sat Jun 30, 2018 8:59 pm

So far this has occurred on 2 DVDs :

Winchester
Tyler Perry's Acrimony

In both I saw an error I have never seen before:

Cells 2-4 were skipped due to cell commands (structure protection?)
Title #47 was added (17 cell(s), 1:57:59)
Cells 2-4 were skipped due to cell commands (structure protection?)
Title #48 was added (19 cell(s), 2:02:06)
Cells 2-4 were skipped due to cell commands (structure protection?)
Title #49 was added (19 cell(s), 2:01:32)
CellWalk algorithm failed (structure protection is too tough?), trying CellTrim algorithm
Cells 1-1 were removed from title start

I was able to eventually save both DVDs but about 10-15 min into the movie, the audio doesn't match with the scene. I have tried burning the dvds on other computers, used both internal and external DVD drives and the result is always the same with one difference. On one computer I didn't get any errors about structure protection but the audio still goes whacky in the same places.

Using MKV 1.12.2 on Win10 and 7.

Acrimony error log attached. I didn't think to save the Winchester log but if I need to reburn it to get it, just let me know.

Code: Select all

Error 'Scsi error - MEDIUM ERROR:UNRECOVERED READ ERROR' occurred while reading '/VIDEO_TS/VTS_29_1.VOB' at offset '12566528'
This is the more significant error. There are parts of the disk that can't be read, and it is possible that the title you selected to save wasn't correct.

Have you cleaned the disk with a soft, damp cloth, and tried ripping it again?
