[PROBLEM] freezes after a certain time of running

Hi , mk01

I did not find it " turn off the TV standby mode with screensaver "
I have only:
in xbmc
Turn CEC capable TV OFF with screensaver = disable
Turn CEC capable TV OFF on RPi shutdown = disable
Turn CEC capable TV ON when XBMC exits = enable
XBMC Dynamic Priority = enable
lower nice priority = 7
higher nice priority = -3

in system\connectiivity:
Force HDMI output when no tv is identified = enable
Ignore HDMI output even if a tv is connected = disable
Ignore CEC init,,preventing wakeup of tv at reboot = disable
Disable CEC = disable
Disable overscan = disable

when i reboot the Xbian, the TV switches to HDMI(where is connected the RPi) via simplink.
If i turn the tv on/off (the RPi is connected and power up)can no longer control the RPi via remote control.
When was power up via TV usb , there were no problems.
But it was a forced shutdown of the RPI, and happened to be the SD card corrupt.
Sorry for my bad bad english.
