    I have captured a few VHS to my computer (.mpg), and from there, I have burned DVDs that I can play on the computer and on my BluRay player. I have sound on the DVDs but not on my .mpg files. While I could swear I had sound on the .mpg files before, let me ask, before I go nuts troubleshooting, can you recover sound from .mpg files, or do they just have sound that can not be played? (They play the pictures okay.)

    Thank you!

    Use MediaInfo on the mpeg files to make sure an audio channel is there.

    Well if you have sound on the dvds made from the mpegs then, assuming you have not added another audio track when authoring, the sound is there.

    Just try a different player. VLC is a good choice. It is possible that you have dis-connected the audio filter or even turned of audio all together

  5. My guess is your DVD player software has a built in AC3 decoder. So you get sound when you play DVDs. But the player you use for MPG your files (which have AC3 audio) does not have an AC3 decoder and you don't have a DirectShow AC3 decoder installed. So that software gives no sound.

    VLC player plays the audio (which, as you suspected, had to be there). Windows Media Player does still not play the files (it did before, that I am certain of now).

    I used Windows Media Player, and I am sure it played the sound before, otherwise I would have posted this thread a week ago

    I have looked in WMP to see if some settings had changed, but I cannot see anything suspicious, and any changes I have tried have not worked.

    Now, I will use VLC player from now on, but it would, of course, be good to know why WMP does not play the .mpg files (it played a music file that I have earlier today, so there is nothing wrong with the player per se, and it is not disconnected from the speakers).

    I had a similar issue with Windows Media Player and Mpeg2 files.

    A quick fix, if you want to use that, is to install ffdshow audio-decoder and ensure that it is used for mp2 audio. The program will be called automatically.

    Your Directshow MP2 audio decoder has stopped working. You could try re-registering quartz.dll.

    You can also try rendering the MPG file with GSpot or GraphStudio.

    Nope. I reregisterd quartz.dll, but still no sound in WMP.

    Thanks, anyway, for the tip.

    I installed and tried, but still no sound in WMP. Any particular setting in ffdshow that I must have?

    From the 'Codecs' menu, scroll to MP1,MP2 - ensure that is not marked as 'disabled'. If it is, or something other than 'libavcodec' is shown, click on the codec to open up the scroll-down menu, select 'libavcodec' and 'OK' to exit.

    When you run a video in WMP, the ffdshow audio-decoder should now show as a minimised icon. Then it is working. This applies for WinXP so I do not know how it would apply to Win7.

    If you're running 64 bit Windows and 64 Bit WMP you need to use 64 bit ffdshow.
    If you're running 64 bit Windows and 32 Bit WMP you need to use 32 bit ffdshow.

    I had the wrong one, now the correct one.

    It is marked "libavcodec".

    The icon that shows is "Haali Media Splitter". It then disappears. And the video shows kinda' frame by frame, that is, it is slow and jerky.

    No sound.

    So where did the haali come from ?

    Did you install a codec pack between the time you got sound and the time you do not get any.

    AFAIK haali should NOT appear as part of the audio process. It would not have been part of the original video process either.

    I see that Haali is installed separately on my computer. It must have come with one of the many apps I have installed the last week. And it must start automatically when I start ffdShow. I do not know why.

    If I installed a codec pack between audio and no audio, I don't know when and how. Maybe a pack was, again, installed with one of the apps.

    I think I just let this rest for the time being. VLC Player works, so I do not need to play these files with WMP. Of course, it would have been better to resolve this problem, but I have to start converting my VHS tapes and get that done before summer is over

    Thank you for your attempt to help. I really appreciated it.

    Regards,

    Fair comment about just using VLC. However I would be concerned if an utility such as haali became invoked just by installing another utility - ffdshow - which itself does not install or even AFAIK use haali.

    If you have been installing a plethorea of utilities lately, and not really understanding what you have installed then you really should take a closer look at your system. Haali, AFAIK, should not have an impact on Mpeg2 playback. I have it installed on my system and I never see it.

    Just as you looked at the ffdshow audio-decoder properties, take a closer look at the video codecs and see what ffdshow is using internally. Now you may wish to set Mpeg2 as 'disabled' so there is no chance of the video-decoder being used. You had playback before so you do not need that now.

    Of course, no two systems are identical and I do not need an Mpeg2 decoder as I already have one installed as part of PowerDVD.

    If haali is mis-behaving then I would uninstall it. If you find you need it later in a different scenario then you can always install it on its own.

    And do have a look for any codec packs. They are bad news with a capital B.

  21. Haai isn't invoked because of ffdshow. Haali is a DirectShow file reader/splitter. It's invoked because the media container has been associated with Haali.

    That is what I expected. Strange though that the OP had playback issues - jerky video - once ffdshow was installed but only apparently had an audio problem before.

    That isn't strange at all. It's an indication that the reader/splitter isn't communicating correctly with the codecs and the output devices (audio and video renderer). It's probably a version incompatibility between Haali and the codecs, or the program that created the video. Or an audio or video driver bug.

    Ok. By why should haali now appear when it was evidently not there before. Unless it was and the OP did not notice it. Except he notices it now and there situation is worse than it was before.

    Would you agree with my prognosis that haali should be uninstalled ?

    Obviously, he installed it at some point. Only popping up now could be be for many reasons. Maybe he uninstalled some other software. Maybe something changed the merit of different decoders.

    He could certainly try it. He may lose the ability to play the containers that Haali supports, MKV, MPEG transport streams, etc.
