I couldn't for the life of me, play 1080i or 720p with the Sempron and
an ATI card.<br><br><div><span class="gmail_quote">On 1/17/06, <b class="gmail_sendername">Chad</b> <<a href="mailto:masterclc@gmail.com">masterclc@gmail.com</a>> wrote:</span><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
