that XvMC was working after seeing the greyscale OSD and the<br>appropriate CPU usage while watching HDTV but now I get tons of "NVP:<br>prebuffering pause" in my mythfrontend log and bad stuttering when<br>watching any type of recording.
<br>The attached errors are when I first start to play a recording, the Xv<br>errors are only at the start and then it turns into a steady stream of<br>prebuffering errors. Does anyone know what causes these?<br>I read on a forum that changing the setuid bit on the mythfrontend
<br>executable could help but it made no difference. I have also tried<br>both the latest 9662 driver and the older driver. I have an Nvidia<br>Geforce FX 5600 card in the machine.<br><br>2006-11-26 23:33:11.216 VideoOutputXv Error: Child A was
