No Sound for WCA videos

I am not getting any sound when I watch the Wing Commander Academy videos. I played them in Windows Media Player and also in The Playa. No sound, but the video is fine.
 
Actually it makes a lot of sense! ;) Think DirectX...

As Kris and others have said, DivX doesn't have superb backwards-compatibility: meaning that newer versions of DivX might not play media coded with older versions. Solution? Get DivX 3.11 Alpha. :)

Bullshit. DivX is perfectly backwards compatible (as far as I ever noticed and also as far) as you can see - the video runs fine.
DivX is a VIDEO codec. It does _NOT_ contain an audio codec. These are two very different parts of an AVI file and in no way interlinked. I could do DivX with an OGGVobis codec for example or with plain WAV encoding.
DivX3.11 Alpha did have a stolen MP3 audio codec bundeled with it (which they named DivX-Audio codec). As they did rewrite DivX from the cracked MS-Video one that ver 3.11 was to 4.0 which was truely original they did not bundle any illegal software (remember Mp3 got copyrights on it) with it anymore to avoid problems.

Now your only problem is to get your hands on a MP3 audio decoder. This should not be too much a problem to find one when you look around a couple of video sites. You probably also won't have a problem to also spot a warez encoder+decoder there.
Alternatively you can install the old DivX-Package that still has that stolen MP3 audio encoder and decoder (it isn't a good one anyhow).

Different DivX Versions work well together on a machine (I got 3.11, Angelprot(IIRC) and Definite DivX - which are all 3.x variants - together with 5.x on my machine without any problems). You cannot keep more then one DivX version >4.0 however (but why would you?) AFAIK.
 
There are many cases where 3.11 content will have video issues if you don't have that particular version installed, I've experienced this myself.

A "DivX" file is a file that uses MPEG-4 for video and MP3 for audio.

While there are several ways to fix the sound problem, the easiest solution is to install 3.11, which you may need anyway.

Thank you for your diplomacy. :(

Clearly not for everyone.

I'm not sure if the DivX-Audio codec is the same as MP3. In any case, the MP3 codec you refer to is a Radium speed-hacked version of the Fraunhofer codec. Not a bad MP3 encoder, second only to LAME, IMHO.

I'm not sure if MP3 encoders themselves are copyrighted - certainly some of them are GPLd.

I'm sure most Windows has an MP3 decoder ACM as part of its multimedia section.

Well I had tons and tons of problems with the different MP4vX formats from MS (mainly v3 IIRC), but never one with Divx3.11.

Yes, I think that is the one. I remember something with Radium and Fraunhofer. However...
There are two versions of that codec a light version and a pro one. Th DivX hack is based on the light one AFAIK. So it is probably quite below their best quality.

If I am not wrong MP3 itself is copyrighted. Not any particular implementation - the whole standard.

Maybe ME and newer. 98SE certainly hasn't, not even with the latest Media Player.

AFAIK, the MPEG standard is open to anyone who wants to join - it's a group effort thing, or somesuch. [In any case, the LAME project is open source.]

Win98 original and newer - it's in the SYSTEM directory, l3codeca.acm, IIRC. [I think this is the 'light' version you speak of, it only encodes up to 56kbps, whereas the Radium hacked one encodes up to the full 320kbps.]
 
I stand corrected. Much of the MP3 standard is patented by Fraunhofer as indicated in this article, but as that article also states, you can avoid those copyrights by using implementation which is not under the patents, which I assume is what LAME has done.
