I have been following the suggestions at <a href="http://www.mythtv.org/wiki/Frame_display_timing" target="_blank">http://www.mythtv.org/wiki/<u></u>Frame_display_timing</a>, but I am not having any success. I have added the udev rule to change permissions on /dev/rtc and verified that they are correct. I have added an entry to /etc/sysctl.conf to set the max-user-freq and verified that it is correct.<br>
