Branching discs

[dh2005]

Hello folks,

Could someone please offer me some advice on this?

I am ripping all of the Blu-rays that I own to BDMV, pulling out the main .M2TS then running that through tsMuxeR (using its "Blu-ray disk" function) to remove all of the extraneous audio and subtitle streams. For branching discs I note that it is first necessary to use ToNMT to boil these rips down to a single .M2TS.

I ran American Gangster through ToNMT and it produced a single .M2TS that works perfectly when run as a file on the C-200. But when I put it through tsMuxeR, although the resultant BDMV runs, I can't change the audio or subtitle tracks without playback locking-up. The C-200 has to be turned off to recover the situation.

What's confusing me is that the file that ToNMT has made works perfectly, and tsMuxeR has never done anything wrong in the past. Why would it mess-up a perfectly functional .M2TS by putting it into a BDMV structure?

I'm using ToNMT 6.0.0, and tsMuxeR 1.10.6.

Any help would be greatly appreciated.

Thanks,



DH.

I will be guessing here as I dont know/use ToNMT, but if ToNMT is roughly joining m2ts files ( as copy /b) without correcting timestamp (& audio gaps/overlaps) than this is the cause, but dunno then single file would also be problematic.

Run it through eac3to to correct audio gaps/overlaps and demux video to raw vc1 file. Then put it to tsMuxeR and mux it to bdmw..

Not sure why it should happen when switching audio, but the symptoms sounds suspiciously like the "PGS subs language set to Undetermined" crash that I and several others have reported some time ago.
Check that any PGS streams in the M2TS are set to *anything other* than "Undetermined" to fix.
You will want to remux into a new BDMV structure when fixing, as manually modifying the main M2TS will not cure the problem.

I thought you kept 100% rips?

Anyhoo are you saying you just want to keep the main movie with no structure for branched discs....from your note it almost reads you want to add the single m2ts to a bluray structure which wouldnt work but i guess thats not what you mean....sounds like you have checked the correct output of tsmuxer

Sorry i cant be more help, as usual...

Would suggest to try demuxing the streams with EAC3TO and remux the resulting files with TSMUXER to BDMV structure. That should at least highlight any errors in the languages, or streams themselves.

ClownBD will do this automate this process for you (remux to .TS/.M2TS/.ISO/BDMW) by the way, so you don't need to run multiple utilities manually.

Cheers,

Thanks for these suggestions, everyone.


... and, Suge; yes, I do keep the full BDMVs on my backup drives, but my playback drives contain remuxes. Saves a little space.

[dh2005]

Okay. I've downloaded ClownBD.

Looks kinda complicated! I've decided to demux with eac3to, then see what I'm left with. Hopefully it'll just be a case of putting these streams into tsMuxeR.

I shouldve know....you know you can just blank out all the extra files very easily dont you without having to remux....ok it keeps extra audio and menus but these arent huge....i just add empty files to replace obvious extras files....might save you a bit of time is all....i think you will still need to remux for branched discs because even the extras will be across many m2ts files but for BDs with an obvious main movie file it works well....10-11gb to be saved on Moon BD for example this way....

Sure. Saving all the space possible is my mission, however...!

Eac3to has run through my Sin City rip. It's reported small audio overlaps at lots of different timecodes, e.g. 26ms overlap at 1:34:16... is this symptomatic of a problem?

You can look at the WIKI for how to use ClownBD, just select "Blu-ray" output instead of ".TS" and you'll get what you need ;-)

Yes, the audio gaps are what EAC3TO fixes, on the previous A-1x0 series, these gaps would cause either lock ups or audio sync drifting by the end of the movie. It's really dependant on how many .M2TS files comprise the movie (maximum I've seen is about 90 in a Disney movie).

It does take longer to remux using EAC3TO as an additional step but it's invaluable for both detecting bad rips and correcting such audio errors. The batch functionality in ClownBD does all my remuxing whilst I'm working.

Even after demuxing the streams with eac3to first, then remuxing with tsMuxeR, the problem remains. And on a different branching disc, so I know the problem's not with American Gangster.

This is odd. I'm gonna use another drive and see whether these abysmal Seagates are to blame.

Nah, it's not the drive.

I'm gonna put it through ClownBD once more, using tsMuxeR within the process rather than after it. If that doesn't work, I give up.
