I'm having a similar problem.
Since RC1 (the 2 May SVN build), MediaPortal's PowerSheduler plugin would put my computer in stand-by after X mintes of inactivity, even if MediaPortal isn't running (only TV Server service running). This has been causing alot of frustration. I've now disabled the PowerScheduler plugin in TV-Server, and my system isn't being suspended anymore. Problem now is, it won't suspend even if MediaPortal is running. |
