Smart Search has apparently stopped working on both our HDDVR's - an HR22/100 and an HR24/500. The guide is populated out to two weeks, and future shows correctly appear in the guide, but a smart search for those shows returns no results. For instance, by scrolling out in the guide we can see multiple showings of "Columbo" - but searching on "Columbo" returns a result of "No shows." Anyone else experienced this? Any info appreciated.
