Although I found a thread describing some fast forward/rewind problems, I haven't found a thread that reports a problem with all the symptoms I am experiencing with my new Roamio Plus here in the Seattle area (Comcast), so here goes: In approximately one out of twenty recordings made from a Season Pass I find this: 1) The info in the My Shows display says "(partial)" and a length of something less than the full show. 2) On the Playing screen, the green bar shows a partial recording, but the length of time shown is different than that shown in the My Shows display. 3) Playing the recording works until I try to fast forward - it begins to go, then gets stuck and displays the same set of images, as if stuck in a loop. The progress hash mark at the bottom just sticks in one spot. 4) Playing through the whole recording wihtout using FF seems to work at times, but trying again sometimes plays just the end of the recording - where according to the displays there isn't any recording. As it plays past the end of the green bar, the progress hash mark again just sticks and doesn't move. All the shows happen to be broadcast on the local Fox affiliate, in HD. I am using a cable card that I moved from my old Tivo HD, where it worked flawlessly for years. There have not been any power failures while these recordings were being made. There are also no overlap issues (gotta love those 6 tuners!). I have called Tivo 3 times so far (case # 130903-015457), and have been given 4 different responses. First I was told the signal strength to the cable card (100, 40 SNR) was too high. When I called Comcast to ask about this, they turned me away as having no problem as long as I see a clear picture (I do). Then I was told I needed to do a Kickstart, but it might totally wipe out the box, along with my 80 some season passes. I declined, and asked for a new box. Before that arrived, I discovered another symptom - after deleting the season passes that made the bad recordings, I could not get the option to create a new season pass for them, despite finding an upcoming broadcast in the guide. I was told to rebuild the guide data, which I did, which fixed the new symptom, but not the original problem. So now I have the new box, but wonder if something about the way I set up the old one caused this problem. I can't seem to find anyone at Tivo who has ever seen or heard of this issue. I'd like to find out more before going through the arduous process of setting up the replacement box.
