I have Windows Vista Home Premium and I downloaded VirtualDub 1.7.8 because I have a project that I want to start working on. I'm using a tutorial for practice before I start my project, so I'm using the files that the tutorial provided. When I tried opening the video file on VirtualDub it said:
Couldn't locate decompressor for format 'WMV3' (unknown)
VirtualDub requires a Video for Windows (VFW) compatible codec to decompress video. DirectShow codecs, such as those used by Windows Media Player, are not suitable.
I searched for a VFW compatible codec that could be used with VirtualDub but it didn't work. Is this just my computer being stupid or did something completely fly over my head? Thank you for helping me out, my mind is completely fried right now.

Add the WMV plugin to the 'plugins' folder in VirtualDub.
Install FFDSHOW and enable WMV.
Enable the WMV decoders under “VFW Configuration” -> “Decoder” -> “Codecs”
or look at the installation guide here.
Thank you. That seemed to do the trick. I'm probably just stupider than I thought XD

sorry for the question but I have problems w/ this program, too.. I've installed all things required, done the things you've recommended here, and it's still not working, cannot find the vfw codec... but I'm sure I have one. I've already had K-Lite codec before, installed DivX codecs... what's the problem?
Thanks for your help, regards.
Which VfW codec?
You'll probably need to find ffdshow's folder in your Start menu, click on 'VFW configuration.' In the window that pops up, make sure you're on the Decoder tab, and that Codecs is highlighted in the left side of the window. Scroll down on the right until you find the codec that VirtualDub can't 'find.' In the Decoder column for that codec, click on the dropdown and set it to libavcodec.
Click OK, then run VirtualDub and see if the problem persists.If cameras add ten pounds, why would people want to eat them?

I've tried what you said, but sadly it doesn't work. Btw I've installed the K-Lite pack, DivX, DivX Pro VFW, Xvid.. that's all I guess. They all worked pretty good with the other editing programs.
And I think it matters that it's VirtualDubMod, not 'only' VirtualDub.
It's an MKV file I want to open, and there are two error messages (if there are, because sometimes it simply froze..):
1. MKV: Subtitle stream (2) contains overlapping subtitles. Some of the may not be kept when editing. ---> I think it's not a big deal since I want to remove the subtitles from this file anyways...
2. Couldn't locate decompressor for format ???? (unknown). VirtualDub requires a Video for Windows (VFW) compatible codec to decompress video. DirectShow codecs, such as those used by Windows Media Payer, are not suitable. Only 'Direct Stream Copy' is available for this video.
VirtualDubMod's support for MKV is rather outdated, and can't handle h.264/AVC video through the VfW interface at all (that's why you get the "Cannot locate decompressor for format ˙˙˙˙" message).
Since all you want to do is remove the subtitle stream, install mkvtoolnix instead, and use MKVMergeGUI (mmg.exe) from the package to delete the subtitle stream. (Uncheck the box next to the subtitle stream, after you've loaded the video, and remux to a new MKV.)
You might also want to install MKVExtractGUI while you're at it, to the same directory as mkvtoolnix, just to have it handy. (You won't need it for the above, but it's useful to have around if you're going to do a lot of work with MKVs.)If cameras add ten pounds, why would people want to eat them?

Right now, I'm using AVIDemux to convert MKVs to AVI. It takes a bit of getting used to, though, and may not run as well depending on your hardware (at least it did in my experience - it runs great on the system listed in my profile, but on the Vista32 system I was using before that (dual-core with 1GB RAM), it ran a lot slower, even with the process priority increased.
You might try some of the ffmpeg/mencoder GUI converters like Avanti and WinFF. It's also possible to frameserve an MKV into VirtualDub/Mod using AVISynth scripts, but that's not for beginners and may require a little experimentation to make sure the video and audio remains in sync.If cameras add ten pounds, why would people want to eat them?
