I recently had the need to trans-code, or re-encode some Windows streaming media files (videos with the .wmv extension). I looked for a simple program to do that for me at my favorite video editing website: http://www.divx-digest.com and was surprised to find that there wasn't a program to help me. My main question is wondering if there is a program that is capable of de-coding .wmv files back to uncompressed .avi files. Since I HAD to start with .wmv files and convert them to .mpg's, I tried several things and was finally successful, although it took several programs to do it. I'll gladly share what I did, but if there is one program that will do it all, I don't want to waste words here in describing how I did it. I did determine that the problem lies in the sound portion of the .wmv files, and all the programs I tried would either lock up, crash, or give me error messages when I attempted the de-coding. Gurus, help me out here, and if need be, I'll describe exactly what I did!!!
Thanks,
Joe (MMG stands for Mix Master General, as I've been involved with remastering poorer quality live audio recordings of several bands.)

it might have been helpfull to at least let us now which ways/tools you tried and were not pleased with!

otherwise we might waste our times listing methods that didnt do the trick for you!

Yes, much sorriness. I should have just listed my method. First, I rip just the video only into an mpg using tmpgenc. Then I take the original .wmv file and just change the extension to .acm (I do believe that is correct, but it's been a few weeks since I trans-coded). Easy CD Creator version 5 recognizes it and can convert the audio to a .wav file. Then I join the audio and video back together as an .avi file using Viftual Dub. Any commets/suggestions would be appreciated, and I thank you for your help.

Even when I use the earlier versions of Virtual Dub; the ones that are supposed to be able to handle Windows streaming media files, I have found that the program does not recognize all .asf/.wmv files. I'll keep doing it the way I described as I have found it to work 100% of the time so far. Of course, I'll keep looking on http://www.divx-digest for the program entitled WMV&ASF2AVI. Hey, I'll write the program myself!!! In one paragraph or less, can you teach me how? (Just kidding).

Thanks for your help.

As far as I know there is not any software or way to actually "un-encode" the video back to it's uncompressed original. You may be able to manipulate a little but when you recieve a encoded/compressed file you can't recover the frames, pixels and other various bits the codec discards as part of the encoding process. Especially when it comes to editing I have to explain to my clients that I have to have the original for the best quality, there is now way to make up for it if you don't have it.

Hope this helps a little
