TiVo Premiere interface occasionally freezes, requires hard reboot

Hi there, for some reason every few weeks the SD interface on my TiVo Premiere (2 tuner, circa 2010) just freezes up completely (even though in the background, judging by the lights that come on, it continues to record scheduled shows, even start and stop recording them). No matter what buttons I press on the remote, I can't get the interface to react. This despite the fact that I see the little yellow light react to every button press.



The only solution is to unplug the TiVo and have it reboot. Is there any magic series of keypresses on the remote that will fix it barring that? BTW, would it have killed TiVo to put a reset button on the unit for these contingencies?
