[mythtv-users] CPU not enough to drive 1080P? Core2duo

It's very unlikely that this particular C2D will have the oomph to play
1080p at anything over a low bitrate.  Yes, cue all the people talking about
how their lower-spec processor is able to play 1080p stuff, etc., etc.   I
have this argument in the IRC channel on a near daily basis.  Stuff people
download is *not* high bitrate and tends to be around 10 Mbit/s.  Real 1080p
material *starts* at about twice that (18 Mbit) and Blu-ray's spec goes up
to 40 Mbit/s.
That said, it's very very very doubtful that anything you're getting from
television is 1080p.  It's far more likely that it's 1080i and that material
should be fairly easy for this machine to handle.  I have heard rumblings
about xv-blit being problematic with 8600 series nvidia cards.  Have you
tried the OpenGL video renderer for this material?  It may work much better
in this case.  Since you are running SVN, you need to have compiled with
--enable-opengl-video, and you can then adjust your playback profiles to
make opengl the renderer across the board.

Let me know.
