mplayer (full screen mode): 60-65%
mplayer (windowed mode): 65-70%

mythfrontend: 95-99%

To clarify, my monitor is running at 1024x768 all the time.  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?

The pauses are still there at 0.5x, but they're much more spread out.  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
0.5xas well--there is an improvement.

I play 1280X720 screen res 1080i HD no problem with a nVidia 5200 on

I'm not sure how well our processes compare, do you have any idea?  All I
know is that mine was fairly good about four years ago.  But it's good to
see that you're not having any problems.

Oh, by the way, all of these tests were done without XvMC, did you want me
to try them with XvMC?

Thanks for the reply anyways,

Cheers,
Dylan
