These streams were tested with PBS 1080i so in windowed mode, on the top-left portion of the channel could be seen on the monitor. So mythfrontend and mplayer (full screen mode) will shrink the stream to fit on the monitor. Does this make sense?

At 0.5x there's about one every 1.5 to 2 seconds where as at 1x there's about one every quarter second or so (much quicker than I realized before). What I'm tyring to get at is the amount of pauses do not simply stretch by
0.5x as well--there is an improvement.<br></div><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">I play 1280X720 screen res 1080i HD no problem with a nVidia 5200 on
