No Sound In Final Bluray Burnt Disc

[basu1801]

Hi,

 

1. I converted an .m2ts file (containing DTS soundtrack) to .toast image file using Toast Titanium 11 (with Bluray/HD Plug-in installed).

2. Then, I burnt the .toast file as a Bluray movie on a BD-R disc using the Toast Titanium 11 Copy (Image File) mode.

3. The resulting Bluray movie has vivid images but NO SOUND.

4. Using MediaInfo Mac I analyzed the final disc. It does have an audio track but it is not DTS but AC3. How did this conversion happen? Was the audio track corrupted during conversion with Toast or is there something I am missing?

5. I have never had a "no sound" problem with my Bluray movies before when I have burnt straight from a .bdmv folder using the same Toast Titanium but in Video (BDMV folder) mode. Is encoding from an .m2ts to .toast causing the problem?

 

Shall appreciate your technical advice.

Did the source have both DTS and AC3 audio? I would expect it to. I don't know how Toast handles DTS audio. When it encodes video it also encodes 2-channel AC3 audio. When it multiplexes video then it leaves the existing audio track as it is. But I don't know whether it also keeps a DTS audio track when multiplexing.

 

If you saw that Toast was encoding rather than multiplexing then go to the custom encoder settings window and choose Never re-encode. Toast may still encode rather than multiplex even with that setting if Toast determines the video doesn't meet Toast's interpretation of the Blu-ray standard.

Many thanks for your prompt response.

1. According to MediaInfo Mac, the source .m2ts file had one Audio Stream only - DTS.

2. As you surmise, that's probably where the problem lies. Perhaps, Toast is unable to process down a DTS stream?

3. As per your advice, tried the "Never Encode" option and re-made the file using Toast. Playback of the opened .bdmv folder continues to suffer from the problem of no sound.

4. In future, if I'm to use Toast for rebuilding an .m2ts file to a "burnable" .bdmv format, should I rip the source file without the DTS audio option and use only AC3?

Toast does support AC3 and if it doesn't re-encode the video the 5.1 or 7.1 AC3 is retained.
