[mythtv-users] Nehemiah Performance

[Tako Schotanus]

You got 16m/8m at 720x480 running with Myth Live TV?
That would be seriously cool because I'm currently using something like
5m/4m at 460x576 to get stutter free video.

But I'm not using those binary drivers you mention but the drivers that
came with the CVS version of XFree86 some months ago.

Did you have to do anything special to get those drivers to work?
(Recompile X like I had to do for example) The reason I ask is that
previous binary drivers I had encountered all seemed to use
functionality/API from X that was not included in the standard RedHat 9
version.

Cheers,
 -Tako
