Question  2012-03-27, 00:13
Greetings,

Since a couple of days i'm experiencing something weird. When XBMC puts my display to sleep the load of my machine starts raising to 100%
A short investigation shows that while the display is off, the following is going on in the log files:

Code:

etc.....

At the same time my Xorg.0.log shows:

Very strange then, because CVideoReferenceClock shouldn't be running when no video is playing.

This seems to be an issue specific to the pvr branch.
