[mythtv-users] "NVP: prebuffering pause" in mythfrontend.log

[nik gibson]

I just installed a new mythtv machine and enabled XvCM.  I confirmed
that XvMC was working after seeing the greyscale OSD and the
appropriate CPU usage while watching HDTV but now I get tons of "NVP:
prebuffering pause" in my mythfrontend log and bad stuttering when
watching any type of recording.
The attached errors are when I first start to play a recording, the Xv
errors are only at the start and then it turns into a steady stream of
prebuffering errors.  Does anyone know what causes these?
I read on a forum that changing the setuid bit on the mythfrontend
executable could help but it made no difference.  I have also tried
both the latest 9662 driver and the older driver.  I have an Nvidia
Geforce FX 5600 card in the machine.
