further DTS-e discussion

[Moviewatcher666]

I have been following the discussion of processing DTS Express tracks in the Bug forum. Hopefully jdobbs appreciates moving from there to a thread on it own. ;-)

So riddle me this! I did a test re-encode of the animated movie 9 with DVDFab's most current version and build. 9 has the DTS-E track on the PIP secondary video. When I played it back in PowerDVD, I was able to hear the DTS-E soundtrack but there was no video. When I played back on my Panasonic Blu-ray player, there was no video or sound.

What is DVDFab doing differently that yields those types of results? I can't tell if I am getting a true DTS-E recode or not.

Anybody have any ideas that might help move the DTS-E issue along further?

you can do a backup without re-encode the main feature only to test the mux i.e.removing only 1 audio or subtitles, if in that backup the the PiP is played with sound is a problem with the encode and not with the remux.

I hope Jdobbs found the way to remux properly the DTS-E track in bdrebuilder.
In the bug reports post someone mentioned that something is posible if you have Nero installed and that software comes with almost every BD-Burner...

I was evaluating MakeMKV, and that has no problems (from what I can see) with demuxing and muxing the DTS-E track - I tried one section of a branching disc and the process time was less than a minute with no sign of any encoding. I checked the MKV output and the track was there and identified as DTS-E - I'm not sure it's of much use in an MKV file with current software players, but it does show that they've either botched it or have identified a straightforward way of doing it.

Seems like we've had that discussion before and the output was actually empty -- but it's been a while and I'm not positive.

I'm going to look at my extracting/remerging code again -- I put a lot of time into it and got frustrated a while back, and I guess I just need to dig-in and find out what's causing the stuttering.

Thanks - I'm sure everyone who is focused on 1:1 backups with compression is most grateful for this.

For information, I have just tested MakeMKV. I took one m2ts file from a branching disc with dts-e (Harry Potter 7A) and used eac3to to create an ac3 file (using Arcsoft codec) which was 7,333kb. I then used MakeMKV to create a single mkv of the same segment and included the dts-e stream. It worked with no errors. I played the mkv in videolan and it showed and allowed to be selected both the main audio and the dts-e one. I then use eac3to on the mkv and produced an ac3 file of the dts-e stream from that. It was also 7,333kb and a binary file compare showed no differences.

@jdobss: if this extracting turns out to be a simple dll that's needed. I'd be happy to supply it from my install. Also the idea we discussed over pm won't be giving you too much trouble ;)

I had success with DVDFab and the DTS-E track of Tokyo Drift, but it seems that the muxing is not totally compliant, PowerDVD 11 and my PS3 played fine (PiP included) the resulting disc, but not Total media theater and PowerDVD 9, after loading the M2TS file to DGNVIndex the info for some streams were erroneous (or totally missing) and BDInfo did not recognised the same streams. :helpful:.

Also, the video quality was so-so.

It was also 7,333kb and a binary file compare showed no differences. I'll follow this logic and see if I can do something similar. Was it reencoded to E-AC3 or AC3? Interestingly I've used AC3 as a secondary successfully on my Sony player. Of course it wouldn't be compliant.

I don't understand the "binary file compare showed no differences"... between what?

[drmih]

Sorry, perhaps I wasn't clear. I wanted to see if MakeMKV was handling the DTS-E correct, or whether as you thought, it was an empty track. Therefore I used eact3to to extract and convert the DTS-E directly into something I could easily listen to (I went to ac3 - I haven't tried but the suggestion is that using the latest release of FFMpeg I could have converted it to E-AC3). I then used MakeMKV to make an mkv file from the orginal source. I checked and this was okay. Finally, to check whether they were properly handling the DTS-E track, I converted the one from the mkv file to ac3. I then compared the one straight from the original m2ts file with the one demuxed and muxed by MakeMKV, and they were the same.

As an aside, I had a quick look at the latest DVDFab. It is now handling the DTS-E track but making a mess of the secondary video. On a Universal tile with U-Control, it does come in correctly but depending on the platform, different results:

Original Disc - small PiP window with mixed audio, PiP being more dominant
TMT - cuts in correctly but PiP window is full screen (obscuring film) and no audio
PowerDVD - audio but no PiP video
Samsung Standalone - Audio but no PiP video
Panasonic Standalone - no audio or video PiP
Sony standalone - no audio or video PiP

Sorry, I was responding to the first post and forgot to put it in quotes.

[jdobbs]

Yeah, I probably should have redirected the thread earlier.
