I have a 140Mb file from WebEx (converted by WebEx Recording Editor from WRF format). When I'm trying to open it in VirtualDub I get a big black screen with a white message "missing codec".
I have ffdshow installed. WMV codecs are enabled there. Also I have a "wmv" plugin installed in /plugins directory in VirtualDub.
Please, help me.
ps. When I save file in WebEx, it says that "Windows Media Video 9 Screen" codec is used for video, and "Windows Media Audio 9.2" for audio.

Did you enable WMV codecs under the VFW decoder setup in ffdshow?
Or just install the WMV9 VCM, http://download.microsoft.com/download/9/8/a/98a6cb2d-6659-485e-b1f9-2c0d9bf6c328/wmv9VCMsetup.exe . I use it and it works fine in Virtualdub.
I installed WMV9 already. Doesn't help.
Actually, I changed "Windows Media Video 9 Screen" to "Windows Media Video 9" and it works. The video works.
But now I have problem with audio. When I'm trying to save AVI from VirtualDub, I get this: "No audio decompressor could be found to decompress the source audio format (source format tag: 0161)"
Any suggestions? THanks!
No chance? Maybe there is some plugin for wma 9.2?

Virtualdub will still not open 6 channel wma files though. I tried opening VC-1 with wma 9 professional and got source format tag 1062.
I've known about the Divx cure for missing codec for wma2 for years but didn't know it would work for 9.2 audio. Need to post this on VDub since a few people there have had problems with 9.2 audio.
I have now the same problem. I have a movie split into three wmv files which I would like to join to one file and correct the aspect ratio of the video. It does not matter what type will be the result, it can be wmv again or (since I will have to re-encode them to correct the aspect ratio) I can could also choose some other codec or other container format.
I first tried to demux or join the files with Windows Media Stream Editor, or Windows Media File Editor, or Windows Media Encoder, but could not figure out how.
I googled further and found out that all this is best done with the VirtualDub. Until now I used VirtualDubMod 188.8.131.52 (build 2366), but it could not open WMV files. I found out that the WMV plugin for VirtualDub requires a newer version, so I downloaded VirtualDub 1.9.8 (build 32706) and copied the plugin files WMV.vdplugin and WMV64.vdplugin into the plugin folder of the newer VirtualDub. I don't know if it helps, since the readme there says that only *vdf files in that folder are loaded (!) but I could not think of another way to install that wmv plugin.
Then I read this thread, installed ffdshow tryouts revision 3299 Mar 3 2010 (msvc 2008, x86, unicode, r) and when installing it, I have chosen WMV1/7, WMV2/8, WMV3/9 to be decoded with libavcodec.
Anyway, nothing of this helped so far and now I don't know what to do. Please help. The problem may be that I cannot find anything like "VFW decoder setup in ffdshow".

Try using ASFJoin to join the files. You'll need to install ASFbin also since ASFJoin is a frontend for asfbin.
I set ffdshow to wmv9 for wmv7,8 and 9 and libavcodec for VC-1
You're problem may be your OS. You are better off using 32 bit Virtualdub and 32 bit codecs in 64 bit OS. there is a trick to installing the 32 bit codecs since MS doesn't have a clue where to put them.
Installing the 32bit version on Windows 64
Extract all the files to a folder
Open up a command prompt (start->run: cmd)
Change directories to sysWOW64 ("cd C:\windows\syswow64")
Type the following (replace example_path with the actual path to the extracted files), then hit enter:
rundll32.exe setupapi.dll,InstallHinfSection DefaultInstall 0 c:\example_path\AC3ACM.inf
