Just saying “failed to open” isn’t going to be enough.ROM drive doesn’t read UHD discs….
You need to post the log/ error message that MakeMkv generated.

I bought mine from HMV in the UK on the release date 17 July and it ripped straight away which I hadn’t expected.

I have already ripped Ultraviolet and my finished product has black bars only left and right, but it has been a while and I can only surmise how I did it though I have attempted a reconstruction. I re-ripped the first episode using MakeMkv and got the black bars all the way round. MKVToolNix has onl...

Northern Exposure (which from my recollection was great) is a rather old tv series and it may need a rather older solution rather than MakeMkv. For a problem rip that I had I dug out DVD Decrypter which hasn’t been updated for years but is closer in age and therefore more likely to be effective give...

I have MKB20_v76_John_Wick-_Chapter_4_7534.tgz as unknown too.
As only submitted on Saturday by another poster I will refrain from reposting for now.

This disc is making me a little concerned. Up to now I haven't dived into the deep deep depths of Dolby Vision playback from a file. I have an Nvidia Shield Pro running Kodi using an mkv envelope and DV is not there yet. I've figured that my tv is only 49", my eyes are less than 20-20, and DV i...

My UK version is ripping away too as I type this.
Thank you, worker elves, wherever/ whoever you are.

I have two LG drives but decided that I needed a non-LG as backup, so I wanted Pioneer. I ordered a Verbatim 43888 from Amazon UK on 14th April 2023, which they had in their warehouse from a 3rd party seller. I figured that if I were to do it, delay was not recommended. I got a Pioneer BDR-UD04 with...

I think that it has BU40N hardware which in theory should mean that it is OK though perhaps needing of a firmware change. Ideally I would like to diversify a bit with a Pioneer based drive but these seem to be in short supply at my favoured supply sources and the firmware change that they are rollin...

I currently have two LG drives, one internal the other external. Between them I manage to backup my UHD discs though of late I have been facing occasional challenges that so far I have managed to overcome by persisting. The internal drive in particular is getting on a bit and this may contribute. If...

Just tried this disc with no success and submitted a dump file this morning,

Volume key not found. File submitted.

I've submitted a file dump for examination on Monday 7 Nov.
