Embed video in HTML what is CLASSID and CODEBASE and PLUGINSPAGE?

I'm interested in embedding video in HTML and have been searching for quite some time. I can make it work, that's not the problem. I want to better understand the CLASSID, CODEBASE, and PLUGINSPAGE parameters. My understanding of those params is for letting your browser which plug-in to use and where to get it if you don't have it. I would like the exact settings for those params when embedding the following: MPEG/MPG, ASF, WMV, MOV, etc..

For example from apple.com for embedding MOVs the following code is given as an example:

<OBJECT CLASSID="clsid:02BF25D5-8C17-4B23-BC80-D3488ABDDC6B" WIDTH="160"HEIGHT="144"
CODEBASE="http://www.apple.com/qtactivex/qtplugin.cab">
<PARAM name="SRC" VALUE="sample.mov">
<PARAM name="AUTOPLAY" VALUE="true">
<PARAM name="CONTROLLER" VALUE="false">
<EMBED SRC="sample.mov" WIDTH="160" HEIGHT="144" AUTOPLAY="true" CONTROLLER="false" PLUGINSPAGE="http://www.apple.com/quicktime/download/">
</EMBED>
</OBJECT>

But how do I find the CLASSID, CODEBASE, and PLUGINSPAGE for other file formats such as MPG, etc.?

So basically I don't want to embed a MPG file and have someone without the proper plugin to be redirected to a QuickTime plug-in page.

I know this is rare that someone would not be able to view an embedded MPG file, but I would like to have enough info when dealing with video in HTML to correct the problem.
