I find it frustrating that this is a Linux only issue. If I had trouble
playing an 1080i stream on a Windows box with a 3 ghz proc, I'd go
crazy. Why is it that Linux has so much trouble with this? I would
think that it would be an easy thing like enabling the correct video
driver or something. I thought maybe my AGP GART stuff could have been
set incorrectly or something.<br><br><div><span class="gmail_quote">On 1/9/06, <b class="gmail_sendername">Steve Adeff</b> <<a href="mailto:adeffs@gmail.com">adeffs@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;">
