    Using Sony DVD Architect Studio.

    I'm creating a authoring project with already muxed MPEG2 compliant files.

    The mv2 and ac3 file were muxed using TMPGEnc.
    The resulting mpeg file plays fine in Media Player with sound (AC3 Codec installed, of course)

    Bringing in the MPEG into Sony's DVD Architect Studio and exporting the TS_* folders with the VOB files and such...

    Burned it with Nero.

    No sound.

    WHY?

    Why would that program even MESS with my MPEG files and ruin the audio?

    Did the vob's on your PC have sound before burning?

    No.
    And only if I use Sony's authoring program.
    I have to use Mp2 in the MPEG.
    If I use AC3, it won't work.

    If I use TMPGEnc DVD Author, even though it doesn't "encode" AC3, it will still acknowledge that there is an AC3 audio stream in the MPEG and will write VOBs with audio.

    WHY SHOULD THE AUTHORING PROGRAM CARE what my audio stream was encoded with?

    Sony's way of saying "screw you" even though the streams were encoded with AC3 audio. Since Sony doesn't like AC3 (in the "studio" water-down version), it won't acknowledge any audio in the MPEG file, so it doesn't write a VOB with audio.

    Is this a normal thing? Or just a Sony dip-!#$!@ thing?

    I'm not asking The DVD Authoring application to re-encode anything. Nor should it... it should just write out the compliant files. ARRRGH.

    In an ideal world all authoring programs would accept any sort of audio and video as long as it is DVD compliant. Unfortunately, as you have found, that is not the case. Some will accept elementary streams, some will not. A decent porgram will accept elementary as well as multiplexed streams, and will accept all of the valid DVD audio and video types.

    Yeah. I'm REALLY ticked off at this Sony DVD Authoring program.
    NOW it wants-with no option from me-to recompress my perfectly fine mpeg file which was multiplexed with a perfectly fine 224kbps mp2 audio stream.

    Dammit straight to hell!

  7. Mine Q's a variation on this theme:

    I recorded a show with ReplayTV, downloaded it to PC. Edited out the commercials with MPG-VCR. I had some hiss on the show, so I demultiplexed the show and ran the audio through Goldwave filter to get the hiss out. The original sound file was 48k, 192 bitrate. I made the mistake of saving the filtered sound file as 44k, 192 bitrate.

    Now, after re-multiplexing, I can view (and hear) the show just fine in Windows MP, but when I try to author the show in either Moviefactory 2 or DVD Architect, the resulting DVD files have no sound.

    My question is, shouldn't I be able to "up-sample" the 44k / 192bitrate sound to 48k / 192bitrate and re-multiplex it, and have the authoring work with sound? 'Cos it's not working that way.

  8. Get ffmpeggui.
    Load your audio.
    Save it as 48khz AC3.
    Import the AC3 into your authoring app.
    AC3 is the dvd standard for audio, mp2 and LPCM are not.

  9. Woo-hoo! The AC3 conversion doesn't work with MF2 (it doesn't do AC3) but it works with DVD Architect.

    Thanks, reboot! You're my hero. I'll be sure to put you in the credits.

    reboot... the problem is...
    My Authoring application refuses to cope with a audio/video stream if it's encoded with AC3 or MP2. Sony DVD Architect Studio only will work with LPCM.

    I have since stopped using it and told Sony to shove it up their... well... you get my drift.

  12. DVD-LAb doesn't take my multiplexed files. It wants to demux it and then muxes it again at time of compilation. is that how your's is reboot?

  13. Yes. DVDLab takes elementary streams, then remuxes during complilation.
    I think the next version will be able to work with mpegs directly (no demux/remux).
