Hello

I understand the basics of HTML and am now in the process of learning CSS.

I've create a simple table that I'd like for those more experienced to check that it's coded correctly please, and if any chances should be made.

Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Video Game Template</title>
<style>
p.tabletext {
	font-family:Arial,Helvetica,sans-serif;
	font-size:1.125em;
	color: rgb(34, 34, 34);
	margin: 0;
}
p.tabletextbold {
	font-family:Arial,Helvetica,sans-serif;
	font-weight:bold;
	font-size:1.125em;
	color: rgb(34, 34, 34);
	margin: 0;
}
table {
	border-collapse:collapse;
	margin-left:auto;
	margin-right:auto;
}
td, th {
	border:0px solid black;
	padding:3px;
}
p {
	font-family:Arial,Helvetica,sans-serif;
	font-size:1em;
	line-height:1.5em;
	color: rgb(34, 34, 34);
	margin: 0;
}
ul, li {
	font-family:Arial,Helvetica,sans-serif;
	font-size:1em;
	line-height:1.5em;
	color: rgb(34, 34, 34);
	margin: 17px;
}
.right {
	text-align:right;
}
.left {
	text-align:left;
}
</style>
</head>
<body>
<table>
<tr>
<td>Insert Video</td>
</table>
<br />
<table>
<tr>
<td class="right"><p class="tabletextbold">Platform:</td>
<td class="left"><p class="tabletext">Xbox (PAL)</td>
</tr>
<tr>
<td class="right"><p class="tabletextbold">Game Condition:</td>
<td class="left"><p class="tabletext">Good</td>
</tr>
<tr>
<td class="right"><p class="tabletextbold">Includes:</td>
<td class="left"><p class="tabletext">Manual, case & cover</td>
</tr>
<tr>
<td class="right"><p class="tabletextbold">Xbox 360 Compatible:</td>
<td class="left"><p class="tabletext">No</td>
</table>
<br />

One improvement I can think of would be the video. This will be an object (You Tube video using old embed code), that I'm not sure how to center correctly, so for the time being I put it inside a table, which I was able to center.

Any advice and or comments would be most welcome.

Thank you
