I got my Elite almost one year ago. I have Comcast with cable card. Hard wired to Netgear router, no Moca, no tuning adapter. I only watch local news live, everything else I record. Within the first few weeks of getting the Tivo I noticed intermittent stuttering when playing back my shows and it continues going on a year later. It comes and goes- I can watch 5 or 10 shows without any stutter, then the next 1 or 2 shows will stutter a few times or be annoying or be just unwatchable. I doubt that it is signal related because it never stutters on live Tv and I have now moved to a completely different house yet the stutter continues. My old house had 5 outlets and I used a drop amp for my cable modem but the signal was clean to the Tivo. At this new house there is just one outlet split right at the outlet for modem and Tivo. I doubt that it is hard drive related because if I rewind the recording and play back the spot where is was stuttering, then there is no stutter! Or if I exit to live Tv then go back and watch the same show later, then the stutter is gone. I doubt it's video out related because it happens whether I am connected directly to my Sony Tv hdmi or through my Onkyo AVR hdmi or to a second Tv in another room via Component. A year later, I am kinda getting sick of it. I've seen other threads/posts about similar stutter. So here are my questions- Is this normal? How much does your Elite/XL4 stutter? Should I use my warranty/BB extension and exchange this thing?
