I have all the opengl support compiled in, and I'm using nVidia
185.18.36 and VDPAU.  There's no performance problem during playback,
but when I exit a recording, it may take around 10 seconds to return
to the recordings page, during which "top" reports mythfrontend using
~100% CPU.  So I was wondering if anyone, especially the gentoo folks,
could recommend Atom-specific options that shorten these delays.  I
can try --enable-proc-opt, but I was hoping that someone could report
their experience on this kind of tuning.

I think I'm using the Qt painter.  I'll try switching it to OpenGL and
see if that makes a difference.
