This is the fastest Quicktime component for playback of DivX, 3ivx, and Xvid encoded movies. It plays movies smoothly that 3ivX and the new DivX 6 codec cannot handle on my 400 MHz G3. I would even go as far as saying that Quicktime playback with FFusion installed is even smoother than VLC. It also has the added bonus of being the best way to play back MS-MPEGv1 and MS-MPEGv2 encoded movies in OS X and is faster than the two individually available Quicktime components. The only problem is it lacks the DivX codec's audio parser that allows playback of .mp3 audio in .avi files. To playback .avi files with audio using FFusion as the decoder, they need to be fixed with DivX Doctor first.
If you have the DivX or 3ivX codecs installed in your Qucktime library then they override the FFusion codec.
I have found that the DivX 6 codec for mac has some serious performance enhancements over previous versions and gives much better playback of high bitrate movies than 3ivx. However, on my slow machine any Divx 5 or XviD encoded movie with a bit rate of around 900 kbits/s or higher is a bit too much even for DivX 6. Doctoring these files with DivX Doctor changes the FourCC of the movie so that decoding will now be handled by FFusion as long as the 3ivX codec is not installed. These movies then play smoothly with sound.
What I recommend is that you install the new DivX 6 codec and use it for playback of the majority of DivX movies but also have FFusion installed for playback of high bitrate movies after they have been run through DivX Doctor. Make sure you do not have the 3ivX codec installed otherwise it will override FFusion on these doctored files.

"Fast, but a pain"

This is definitely a lot faster than the offical DivX codec, but it lacks DivX's AVi audio parser, meaning you need to dance and prance with DivX Doctor to get audio that works. Thanks, but I really don't miss those days.

I'm sticking with my old setup of DivX + 3ivx. If you install both codecs, you get the best of both worlds: DivX parses the audio so you can just open your AVIs and have them WORK, and 3ivx handles the actual video decoding. In my limited testing, I didn't notice FFusion to be significantly faster than 3ivx, so I see no reason to use it.

If FFusion could override DivX's video decoding like 3ivx does, I'd at least test it further, but as it is, there's no way I'll use this. Doctoring movies is just too much of a pain.
