Trying 0718b with advanced deinterlacing and overlock:

core_freq=500
v3d_freq=500
h264_freq=500
over_voltage=4

and

echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

So far everything is working well after an hour or two of live TV, no weird stuck navigation . Thanks for working through this!
