[mythtv-users] Unreasonably high CPU usage when playing HD content? Suggestions?

[Jason Keirstead]

Hi. No it is a "modern" one as I posted - a dual core AMD X2 6400 running at
3.2 Ghz. It should have absolutely no problem playing h.264 HD content- and
thi sis not even that.

I think it is the ATi video drivers myself. I am just wondering if anyone
can verify this before I go buy a new card. Are the fglrx AVIVO drivers
really THIS bad?

In theory, there is no difference between theory and practice. But, in
practice, there is.
