Ok Pieces of this and pieces of that and i got this working !!

PHP Code:

Create a New User Profile Field - Single-Line Text Box
Title -    YouTube Video In Your Profile 
Description -     You can give your YouTube a title here
Hidden - Yes
Searchable - NO
Memberlist - NO

[B]Note the Field Number not the order number [/B]

Mine was field 12 

Edit This code with your field number (Replace all the 12's)

<if condition="$userinfo[field12]">
<table class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" border="0" width="100%" align="center">
<tr>    
    <td class="tcat">$userinfo[username]'s Video <if condition="$post[field12]">&nbsp;-&nbsp;$userinfo[field12]</if></td>
</tr>
</table>
<table class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" border="0" width="100%" align="center">
<tr>
<td class="alt2" style="border-bottom:0px solid $stylevar[tborder_bgcolor]" width="200" colspan="2">
<center>    
<object width="425" height="350"><param name="movie" value="http://www.youtube.com/v/$userinfo[field12]"></param><param name="wmode" value="transparent"></param><embed src="http://www.youtube.com/v/$userinfo[field12]" type="application/x-shockwave-flash" wmode="transparent" width="230" height="230"></embed></object>
</center></td></tr></table></if>
<br>

Then
Put it in Member Info Template Between 
<!-- sidebar -->
and
<!-- / sidebar -->

Like so : (I moved the Friends Down )
    <!-- sidebar -->
    $template_hook[profile_right_first]
    $blocks[stats_mini]
    $template_hook[profile_right_mini]
<if condition="$userinfo[field12]">
<table class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" border="0" width="100%" align="center">
<tr>    
    <td class="tcat">$userinfo[username]'s Video <if condition="$post[field12]">&nbsp;-&nbsp;$userinfo[field12]</if></td>
</tr>
</table>
<table class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" border="0" width="100%" align="center">
<tr>
<td class="alt2" style="border-bottom:0px solid $stylevar[tborder_bgcolor]" width="200" colspan="2">
<center>    
<object width="425" height="350"><param name="movie" value="http://www.youtube.com/v/$userinfo[field12]"></param><param name="wmode" value="transparent"></param><embed src="http://www.youtube.com/v/$userinfo[field12]" type="application/x-shockwave-flash" wmode="transparent" width="230" height="230"></embed></object>
</center></td></tr></table></if>
<br>
    $blocks[albums]
    $template_hook[profile_right_album]
$blocks[friends_mini]
    $blocks[groups]
    $blocks[visitors]
    $template_hook[profile_right_last]
    <!-- / sidebar -->
