Three times now, on my new DirecTV tivo, my queue (live buffer) has disappeared. Let me state that I am NOT a TIVO novice, I have had a TIVO since the very first 9 hour SD tivo back in the day. I know all the ways that you can release your queue (live buffer), like by changing channels, etc. But this bug, I have never seen before. You have 30 minutes of queue, and you are perhaps in the middle of that queue, and suddenly, the screen goes black, and you are brought to live tv, with no green queue left. The TIVO was not suddenly recording a program on the same channel, as I have seen that be the cause. Nope, this is just a sudden loss of queue for apparently no reason. I do know that at some early morning hour TIVO will change to something like channel 1, to download a "note" or video for the "commercial", and this is not the case either. Other than this, i have seen no other issues, like you might if the hard drive was failing or something. So, maybe its just a bad unit, or has some bad sectors, who knows, in which case, maybe I get a new unit. So, curious, as to whether anybody else has had this strange occurance?
