I wonder if these particular discs are just some sort of corruption as it complains of corrupt IFO even though no read errors.

After trying to re-rip over 100 I have a short list of discs which immediately refuse to open but play OK in an HDDVD player:

That is a bad disc / rot, my disc copied fine.

I'm re-ripping some of my HDDVDs and have some that wont rip but do not have any read errors.

These ones are detected as HDDVD but immediately say failed to open with no other error given:
Pans Labyrinth - Newline USA
Charlie And The Chocolate Factory - Warner USA
Tideland - Concorde Germany

I'm re-ripping some of my HDDVD to fix issues with 256 SPF DD+ Audio. The first time I ripped them was a long time ago with V1.6.X and V1.7.X.

Some of the discs I previously ripped with these old version do load but the main feature is missing from the titles list. I've only tried 6 so far and had ...

One test you should try. Rip the disc to a decrypted folder backup with makemkv. Then use mkvtoolnix on the backup folder to create the mkv, selecting the right playlist file in mkvtoolnix. Try playing that on the ugoos and see if the same problems exist. This will determine if it's a makemkv ...

I have this disc and there are multiple issues with the rip:

1. When ripped to MKV the Dolby Vision pulses brigtness changes constantly (This does not happen with a decrypted M2TS rip so I would guess is a MakeMKV issue)
2. The video playback is a bit choppy on my AM6B+ (Audio is fine, I guess ...

I have a rip from a 4K disc of mine which the Dolby Vision layers brightness pulses constantly (Its horrible) but a backup of the same disc using the same hardware works well. Does anyone know if this is likely a MakeMKV bug or UGoos AM6B software issue? The disc is slightly unusual in that it is ...

Get the ugoos, all the other devices drop frames with FEL playback. CPM A14 has perfect playback and doesn't really need any update so we are good forever...


I find PVR/TV playback has severe audio sync issues with the CPM build.

CPM was well into supporting more multi channel PCM formats that ...

The issue is a Kodi bug. Universal HDDVDs use DD+ at 256 samples per frame, normal DD+ is 1536 SPF. The player / player software must combine smaller audio frames like this into one larger frame to send over HDMI. Kodi correctly creates the larger frame but then sends duff audio frames so for a ...

Has anyone else noticed the issues with the Extremely high bit rate Beatles Atmos in Kodi?

I wonder if the issue with variable size TrueHD packets will be come more common. Still hoping the Kodi team will fix DD+ 256SPF bitstreaming too but since this ...

I'm using a Kodi build I did.

I think it might be the additional MVC code added to Kodi because if I remove the right eye first marker in the MKV it works (After just manually activating switch eyes in the GUI).

If anyone has successfully watched any of the following as 3D MKV please let me know:
- Bait
- The Boss Baby
- The Chronicles of Narnia: The Voyage of the Dawn Trader
- The Darkest Hour
- Dolphin Tale
- Drive Angry
- Edge of Tomorrow
- Ghostbusters (2016)
- Gulliver's Travels
- The Hobbit: An ...

Thanks.

This isnt related to 1.15.2, happens with older versions too.

Same for me with Kodi. The MVC codec does not get used with rips from 1.15.2, they just use the standard H264 codec and show in 2D.
