Default Timed out waiting for free video buffers

I've got a MythTV box (FC4) w/ FX5200 that after watching live TV for a random amount of time X will freeze with ~90% CPU usage and the MythFrontend log is spewing out:

NVRM: Timed out waiting for free video buffers

In my xorg.conf file I'm using 'nvidia' for the driver, have RenderExtensions(sp?) disabled, don't have OpenGL V/Sync enabled.

Does anyone know what causes this behavior and if there is any way to correct it?

I have no idea, but I think when it happened to me I would start looking at the interrupt assigned to the card. Is it shared with something else, then try to change that.

I tried messing around with the IRQs. Disabled the onboard NIC that was sharing an IRQ with the video card, disabled USB to free up IRQs. None of that seemed to help.

What has seemed to fix the problem (fingers crossed) is that in xorg.conf I set Option "NvAGP" "0" to disable AGP. Slightly higher CPU usage (I think), but seems to perform ok.
