That would indicate a network issue. Look at the memory and network statistics in Task Manager. Do they climb high and stay there for a long time? If you think you've got a gigabit connection but the network throughput won't go over 100Mb/s, you may have a bad cable or switch port. MakeMKV can queue...

Two possibilities. First - your playback program does not support the codec used for the audio, but your DVD player does. Test the MKV file with VLC, which understands pretty much all the audio codecs used in DVD and BD commercial disks, to see if it really is there. Second - you have set a "preferr...

MakeMKV outputs what is on the disk. DVDs are, by standard, interlaced video.

You can post-process the video to attempt to remove the interlacing, but MakeMKV is always going to copy what is on the disk itself.

Since MakeMKV won't write MP4 files, and you say it creates an MKV file without error, the problem is with the conversion... Can you play the MKV file generated by MakeMKV? Given that the problem with the conversion to MP4 occurs with more than one encoder would probably indicate that the encoder ca...

Guessing from your log that you're using an external USB-powered drive. It reaches a part of the movie where it can read faster, then runs out of USB power and shuts down. Make sure the drive is plugged into a FULLY POWERED USB port (not a hub, unless it has its own power supply), and try the rip ag...

The actual debug log is more valuable than _private_data.tar.

Write protect errors are on the media being written to, not the optical disk. How are you on space on your target device? Are there any per-user space limits?

Since the standards for UHD didn't come about until a year after that, though, it would be strange that the hardware would be UHD-capable. The original "BD-XL" standard, which goes back further than that, did not have a high-enough bit density. If I remember correctly, the original BD-XL was 25GB/la...

The track header in the MKV file has to have some information, since handbrake can accurately determine things like channel counts and bit rates when it reads them.

No, the automatic-as-needed download, which your log says failed. You probably have to change your DNS settings to use one that doesn't censor domains. There is a lot of discussion about this in this topic , but the takeaway is that using Google's DNS at 8.8.4.4 or 8.8.8.8 is more likely to find fai...

You need a USB flash drive that is at least as big as what you're ripping. DVDs can be done with a 16GB flash drive. Format the drive as either NTFS (if you're using Windows or Linux) or ExFAT (for Windows and MacOS), and make it the target of your rip. The slow write speed of a flash drive will lim...

Since others have decrypted it, have you verified that you are able to download the Hash Key file?

If you are using the current hash key file and MakeMKV still says it can't find a key, submit the generated .tgz file (location should be shown in your log) to svq@makemkv.com for analysis.

You're using a DVD-only drive, so you already have the advantage of using a red laser instead of a blue laser. HOWEVER, I didn't notice one key thing in your logs - the initial error occurs fairly deep into the read, when the disk would be spinning fast, and the drive then goes off-line for a while....

MakeMKV cannot correct for unreadable disks.

Your drive is having problems reading large areas of the disk, so you should start by trying to clean it.

DVDs are interlaced, and MakeMKV copies the video as-is into the MKV file.

Removing interlacing isn't simple. Handbrake does a pretty good job if you select one of the DVD-oriented presets, but sometimes you have to force its hand a bit.

Are they Bluray, or UHD? Your drive cannot read UHD without the proper firmware.
