I ran into a strange issue a couple weeks ago. I recorded a new episode of The Office, but when trying to play it back, nothing happens. When trying to play it, the screen flashes for a second and then just goes back to live TV. All of my other recordings work. My DVR box is only about 50% full. I tried powering off the DVR box, but that didn't help. Eventually ended up deleting this recording.
Two weeks later it happened again, this time with a different show.
Thoughts?
