If your processor could handle HD decoding, your video card would
handle the downconverting on playback. You could avoid the
digital-analog-digital round trip while still using your current
display. <br>

I don't know how much recording you do on a daily basis, but
transcoding from HD to SD will probably take you 3 hours for every hour
of video recorded.<br><br><div><span class="gmail_quote">On 12/4/05, <b class="gmail_sendername">glen martin</b> <<a href="mailto:lists@locutory.org">lists@locutory.org</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;">
