Sure you're not having poor signal problems or power issues? Reboots will do this, of course, but you'd not get the total to be 60 minutes, as was said. It takes a minute or so for the unit to reboot!
Signal drops could cause it to end the recording and come badk with a new one. Anything between your antenna and the station? Or, if this was from the sat HD feeds, any bad weather, etc.?
