You can use ffmpegX to convert the file.
Not if the file uses WMV3. ffmpegX, like VLC and MPlayer, cannot decode WMV3. ffmpegX is based on the same tools as VLC and MPlayer, so in general, if they can't play it, ffmpegX can't convert it.

I tried two different .avi files.
The one where only the sound wasn't working is Windows Media Video 9 Standard Format.
Wait...to clarify, you mean that the sound WAS working, and the video was NOT, right? That would be normal. VLC and MPlayer can't play WMV3 (Windows Media Player 9 Video). The only ways to play WMV3 on the Mac are Windows Media Player, which can't play AVIs, and QuickTime Player using Flip4Mac's WMV component, which, again, doesn't play AVIs (at least it didn't last time I checked). Bah.
There is one way to convert it on the Mac, although it doesn't seem completely reliable. That is, oddly enough, with VLC. It doesn't matter that it can't play the video, because we won't be converting the video we'll just be dumping it into a WMV file. Here's how:
1. Add your AVI to VLC's playlist.
2. In VLC, go to File > Streaming/Exporting Wizard.
3. Select "transcode/save to file" and click Next.
4. Select "Existing Playlist Item" and your AVI from the list, and click Next.
5. Check the "Transcode Audio" box. DO NOT CHECK the "Transcode Video" box. In the audio codec menu, select mp3, and click Next. You might want to change the bitrate, too. Up to you.
6. Select "ASF" (this is another name for the WMV file format), and click Next.
7. Choose a place to save the file, click Next, and then click Finish.
8. Once VLC is done with the conversion, open your ASF file in QuickTime Player (be sure you have Flip4Mac's WMV Player installed).
This method should at least give you proper video. As for the audio...ironically, that's what's given me trouble. Go figure! The audio VLC produced was an octave or two lower than it should have been, which is very odd since VLC plays the audio straight from the source file just fine (I just get no video). I assume this was because I was dealing with an MKV file, though. I hope it will work fine with AVIs, but I've never personally tested it.
Good luck!
As for the file that makes everything crash, if you get info on it in MPlayer, what does it say? What format, codecs, etc?
