I had the week off from work for Fourth of July. I had been running tvheadend for almost two years now and my subscription for Schedules Direct is coming up, so out of boredom, I revisited my OTA DVR setup.
I've been playing around with: NextPVR (on Windows), Tablo (since I have a lifetime subscription), Silicondust's HD Homerun DVR service and now Plex DVR.
I'll write something more detailed up. Last year I did a write up also, I'm seeing if things have changed.
