Last night I had a few minutes of the buffer that would not go away. It was from another channel. So if I tried to change channels, it would always start at the beginning of this stuck buffer, then when it would get to the end it would jump back to the beginning of the buffer but would be showing the channel it was on. The buffer would never increase in size. I first tried rebooting the Mini and it didn't help. Then I went to the Elite and told it not to share any tuners. So I then changed all tuners to a different channel to reset the buffers. Which they were. I then rebooted the Mini again. Then I shared the one tuner from the Elite again and when I looked at the Mini I still had that few minutes of buffer stuck again. The only thing that fixed this buffer issue was to reboot the Elite. Once it came back up everything was fine. I have not seen this before.
