I noticed this weekend that everytime I come out of watching a recorded show that the live buffer on one of the tuners is always lost. Is this normal? I constantly switch between the two tuners and use the buffer to see what I have missed. Sometimes when I'm caught up on both or whatever I am watching gets boring I will watch a little recorded TV. I'm another person coming over from the D* HD Tivo and I'm used to both tuners having the buffer available. But it seems to only keep the one I wasn't watching when I went to the recorded show. Is this because I also and using the OTA?
