In addition to the hard reboot, try a different HDMI cable. When I first hooked up my FIos my picture was flickering off and on. Switched to a better HDMI cable and it has been working fine since. Good luck.
Every ten seconds it started freezing for ten seconds and then work and then freeze, etc. I unplugged the pass through and hooked the dvr straight to my tv and it worked fine. Pretty pissed, wtf. I use Verizon FiOS BTW.
