It is important to clarify a common mistake. When people see a file with a
<tt class="filename">.AVI</tt> extension, they immediately conclude that it is
not an MPEG file. That is not true. At least not entirely. Contrary to
popular belief such a file <span class="emphasis"><em>can</em></span> contain MPEG-1 video.
</p><p>
You see, a <span class="bold"><strong>codec</strong></span> is not the same as a
<span class="bold"><strong>container format</strong></span>.
Examples of video <span class="bold"><strong>codecs</strong></span> are: MPEG-1, MPEG-2,
MPEG-4 (DivX), Indeo5, 3ivx.
Examples of container <span class="bold"><strong>formats</strong></span> are: MPG, AVI, ASF.
</p><p>
In theory, you can put an OpenDivX video and MP3 audio
into an <span class="bold"><strong>MPG container</strong></span>. However, most
players will not play it, since they expect MPEG-1 video and MP2 audio (unlike
<span class="bold"><strong>AVI</strong></span>, <span class="bold"><strong>MPG</strong></span>
does not have the necessary fields to describe its video and audio streams).
Or you might put MPEG-1 video into an AVI file.
