Using an HR10-250 with 2 satellite inputs and 1 OTA input connected: I had set Smallville to record (from an OTA HD channel) on a seasons pass. I tuned to that channel a few minutes before it was scheduled to start but then turned off the TV a minute after it started. When I turned on the TV again in about a half hour, it was on Smallville but I wanted to change the channel to a satellite SD channel. When I tried, I was prompted that I needed to stop recording Smallville in order to change the channel. I checked the Now Playing List and confirmed that Smallville was the ONLY show being recorded. So, in other words, I was not able to record one show and watch another. I have tried to recreate this problem but haven't been able to. Any idea what may have caused this to happen?
