At first I thought it was a fluke, but I'm getting zero second recordings again. There have been three of them so far, all from satellite-delivered channels (not OTA). Before this episode, it must have been about six months since my last ZSR. Signal strengths are all good. I haven't made any changes. The only change that I have identified so far is L273. I forced a reboot a couple of times. Maybe that will help. The sad part is that I was beginning to depend on my 921 to record reliably again. This really sucks!
