I have a video file that uses a rare vorbis codec. Mediainfo lists it as Vorbis (Mode 3+). It's this one here http://www.videohelp.com/tools/OGG-Vorbis-ACM-Codec
I installed it on my Win7 64 computer but it doesn't work. The .inf installs the vorbis.acm in the System32 folder. When that didn't work I copied it to the SysWOW64 folder but that doesn't work either.
When I had WinXP this codec installed and worked fine.
I read a thread by someone with the same problem and they said they extracted the audio stream with mkvtoolnix and then converted the vorbis to some other format. I decided to do that but it wouldn't let me extract the audio stream. It gave me an error: format 0x6771 for this audio track.
So how can I extract the audio stream and convert it? I don't even care about getting the audio codec to work anymore. I'd rather just convert the audio to another format and not have to worry about it again.

It will only show up in 32 bit apps.
Actually I discovered I'm able to hear the audio, but only when it's an audio file. If it's video and audio then it doesn't work for some reason; MPC-HC gives me an error saying: The following pins failed to find a connectable filter:: LAV Splitter Source::Audio.
But it's ok. I was able to use VirtualDub to extract the audio stream as a .wav and then I converted the .wav to .mp3 using Audacity and then muxed it back in VirtualDub and it works. Now I hope I never run into this stupid audio codec again. Thanks.
