why does virtualdub say error on ACM audio if ACM codec is installed ?

Because your AAC audio is corrupt. If you have fccHandler's ACM codec, it searches for certain information in the header (http://forum.doom9.org/showthread.php?p=1639389#post1639389), and if they aren't there, it'll tell VD it can't decode this. Since you don't have anything else that can decode 0x00ff, you get "Missing codec". Since most AAC-in-AVI is written incorrectly, that ACM codec is pretty much useless.

Why the hell are you using AVC+AAC in AVI anyway? Use MP4 and another editor like avidemux and your problems go away.

Foxy, I think Auto is opening an .FLV, not .AVI (note the FLV plugin (https://sourceforge.net/projects/fcchandler/files/))
Auto, you don't quote the error message (hint: View menu, Log, right-click, Copy)
I think you'll have better luck with the FFMpeg Input plugin (http://forums.virtualdub.org/index.php?act=ST&f=7&t=20025&st=120#entry94860) anyway.

I have installed and placed the plugin filters in my virtualdub plugin folder, How ever when I load the video , the flv plugin Loads instead of the newly plugin I just installed, how do I turn off the flv plugin and make sure the ffmpeg input plugin loads instead ?

I always use: File menu; Open video; Select files of type="FFMpeg Supported Files"; select the file. A bit clumsy, I know.

To remove any plugin, simply move it from the plugin folder to some other folder. You can always move it back later if you want to.

thanks foxy,
I just tried avidemux for the 1st time, and have a problem already.
My plan was to convert only the audio to mp3, from AAC , but when I wanted to play the finished new converted video- nothing happened, now none of my players can play this new one. I would like to know what I did wrong ? here is the screen shot -

After I simply move it from the plugin folder to some other folder and then try to load the video in virtualdub ,it complains " video.mp4 is of an unknown or unsupported file type". removing that flv plugin stopped it from Loading.

1. Are you working with VirtualDub, 32 bit version?

2. Are the following files in your Plugins32 folder?
* FFInputDriver.vdplugin?
* ffdlls subdirectory, containing 4 DLL files?

3. Under File menu; Open video; Select files of type: do you see "FFMpeg Supported Files" ?
