No audio with "Kill Bill" blu-ray MKVs

#1 Post by rajmahid » Wed Jun 26, 2013 6:24 pm

This is the first time I've run into this problem with ripping my blu-ray DVDs to MKV, but after creating MKV versions of the main movie of each blu-ray disc (1 & 2), I tried playing them on VLC and got an error message: "No suitable decoder module - "undf". I figured that was a VLC issue, so I streamed them to my Oppo 105 player, but still no sound whatsoever -- regardless of which audio mode I selected.

I re-ripped both movies to MKV again -- making absolutely certain I'd checked the audio stream boxes -- but still the same thing...no audio when streaming to my Oppo, and the same VLC error message when I tried playing them (which I usually do to test/preview an MKV ). :( I never got an error message while MakeMKV was creating each of the MKVs -- everything appeared to work perfectly during the process and upon completion.

Is this a known problem with some blu-ray movies? I've ripped over 25 of my BD movies to MKV with no such issue...and ripped a different blu-ray movie to make sure nothing had changed -- and the resulting MKV had the all the audio tracks.

Any clue would be helpful.

Which audio streams did you select? Some, such as "TruHD", are not well supported in software.

Search the forum for "undf" and "undef", and you will find several topics on this.

I'll check to see when I get back home, but I always select all the available audio streams when ripping and let my player default to the first one it sees; I can always select another one if the first one isn't to my liking. Many of the blu-ray movies I've ripped to mkv have TruHD that's easily detected by my Oppo player. Is this a fluke or the Oppo?

Thanks for the tip...I'll search for 'undf' and 'undef' to find the answer to my query.

FWIW, I downloaded a trial version of the latest DVDFab just for the heck of it. After a little research, I was able to create an mkv of my 'Kill Bill' blu-rays that didn't have this issue. And this was with no transcoding -- a 1:1 mkv of the main feature. Go figure... ')

You're confusing your codecs. VLC handles TrueHD just fine, what it doesn't like is WAVEX-in-MKV (MakeMKV converts LPCM to it by default, to preserve channel mask/ordering information which is not possible with raw PCM).
