Trying to embed a video file in HTML5: ERROR=No video with supported format and MIME type found?

Question

Hello all!
I am desparate for a solution. I am testing my site on Firefox and Explorer and still no sign of a functional video yet.
Firefox: I get the error: No video with supported format and MIME type found.
Explorer: I just get a distorted layout.
Here is the code I am working on:
<table id="Table_01" width="480" height="801" border="0" cellpadding="0" cellspacing="0">
    <tr>
        <td colspan="6">
            <img src="images/Video_01.jpg" width="480" height="114" alt=""></td>
    </tr>
    <tr>
        <td rowspan="3">
            <img src="images/Video_02.jpg" width="52" height="486" alt=""></td>
        <td colspan="4">
           <video controls width="376" height="221">
             <source src="C:\Users\aalmeida\Videos\AEMC PEL 103 6 Channel, Power & Energy Logger - with Display (Part 1).mp4" type="Video/Mp4"/>
             <source src="C:\Users\aalmeida\Videos\AEMC PEL 103 6 Channel, Power & Energy Logger - with Display (Part 1).webm" type="Video/WebM"/>
             <source src="C:\Users\aalmeida\Videos\AEMC PEL 103 6 Channel, Power & Energy Logger - with Display (Part 1).oggtheora.ogv" type="Video/Ogg"/>
             </video>
Please tell me that there is something missing in the code. I have spent a lot of time uninstalling-updating Firefox plugins, added MIME types in the Internet Information Manager (I'm on Windows 7)
and  seriuously hit a dead end with this!
Any advice would be muchly appreciated!!!
Thanks

As Jon said, you must declare the page as HTML5.
And your server may not be set up to deliver video as a binary file if it is an .OGG file. I have not seen this problem with .MP4 or .M4V in the past, but every server is a little different.
To add a MIME type, you need to change your .htaccess file on an Apache server thusly:
AddType audio/ogg .oga
AddType video/ogg .ogv
AddType application/ogg .ogg
AddHandler application-ogg .ogg .ogv .oga
Additionally, MIME types can usually be changed on a server's Control Panel. One can also ask one's hosting provider to do this as well.
Firefox makes it necessary to use OGG files. Webkit-based browsers will deal with .M4V or .MP4 and I understand Internet Exploder will work with the latter two as well.
