Question to those who typeset email letters under outlook?

Question

Outlook

It is required to make a block with a background in the form of a picture - and inside it a button with a rounding
. I'm trying to do it this way:

<table>
    <tr>
        <td background="http://galiy-web.ru/email-images/header-bg.jpg" width="100%"
            style="background-image:url(http://galiy-web.ru/email-images/header-bg.jpg)" bgcolor="#71d6ff"
            height="250"
            valign="top" align="center">
            <!--[if gte mso 9]>
            <v:rect xmlns:v="urn:schemas-microsoft-com:vml" fill="true" stroke="false"
                    style="width:520px;height:250px;">
                <v:fill type="tile" src="http://galiy-web.ru/email-images/header-bg.jpg" color="#71d6ff"/>
                <v:textbox inset="0,0,0,0">
            <![endif]-->
            <div>
                <table width="100%" cellpadding="0" cellspacing="0" border="0">
                    <tr>

                                    <center>
                                <![endif]-->

                                <!--[if !mso]><!-->

                                </center>
                                <!--[endif]-->

                                <!--[if mso]>
                                </center>
                                </v:roundrect>
                                <![endif]--></div>
                        </td>
                    </tr>
                </table>
            </div>
            <!--[if gte mso 9]>
            </v:textbox>
            </v:rect>
            <![endif]-->
        </td>
    </tr>
</table>

But along the way, nesting mso comments does not work?
Since the background in the form of a picture in outlook is shown, but the button inside it is not. It turns out that either the background or the rounded button works - when you disable each mso comment in turn.
