I am currently running 1.17 without any issues. However if I upgrade to later version including 1.20 system fails to respond after resume or TV power off/on. Killing Mediaportal process and re-running gets things working again. OS is Windows 7 Home 64bit, TV is attached via HDMI thru an Amp. Logs from 1.20 attached I simply start MP stay on main menu turn TV off and on -> MP locked up so have to kill it.
