[mythtv-users] MythMusic/visualisations 100% CPU

I'm sure this has been remarked on before (like here 
but I haven't yet been able to find an answer...

Basically, everything I do in Myth uses almost no CPU (typically 1-2% load 
when watching/playing back TV) except for the visualisations in MythMusic. 
Top reports X and Mythfrontend using about 45% CPU when the viz are in 
"tiny" mode, and completely thrash the system when I pop them up to 
fullscreen. This is on a Athlon 2400 displaying at 1280 by 1024.

I'm using a boring GeForceFX MX 4something-or-other, and have tried 
compiling myth with and without support for the nvidia overlay stuff, which 
doesn't seem to make a blind bit of difference CPU-wise (and of course 
losing my colours in the OSD). I'm using the latest stable version of the 
gentoo nvidia ebuild, namely 1.0.4496-r3. I switch to the xfree GLX to 
compile myth, and then back to nvidia GLX once it's done, as per ebuild 

Anyone have any ideas how I can get the GFX card to help with the viz?

Much obliged for any input, even if it's an RTFM or STFW ;^)
