That's a good trick.
But I've now double/triple checked things, and the setup didn't/doesn't
have that "zoom by one" thing set -- I must have gotten rid of it at some point.
So, the GT430 stutters sometimes, even on "normal" 1920x1080 playback.
Which is odd, because my Atom/Ion2 box can play the same content
without the stutter, and there's no way the GT430 is slower than Ion2! :)
That's even with the clocks set to "performance" in nvidia-settings.
So, something else is affecting things. One difference between the Atom/Ion2
box and the larger GT430 box, is the former uses XFCE whereas the latter
has a "normal" Gnome2 desktop underneath mythfrontend.
I seem to recall that the Ion2 box did stutter when I originally set it
up with GNOME, which is why it now has XFCE. The other box had no issues
with GNOME when originally set up with a 9500GT, and later with a GT240.
So.. I might try and get an XFCE desktop going on that box,
or perhaps work at trying to shoehord the (double-slot width) GT240 card
back into it again.
