Do all Tivo's Stutter when playing recorded shows?

    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?

    The only time my Elite stutters is on playback and only when it is in the process of a network connection to the TiVo servers.

    I can 99% guarantee that if I force a network connection it will start stuttering. Does not matter if any tuners are recording, but it is worse when they are. Rewind and it will not stutter in the same place.

    I don't see the stutter issue myself, but what I do see is my Elite is very sluggish in responding to commands in HDUI. I think the main problem is the processor in the Elite is just barely beefy enough to handle 4 tuner load. My 2 tuner units have always been more responsive and the Mini just blows my other units away as far as responsiveness.

    As an experiment what you can try is for other tuners that are not currently recording anything tune them to channels you don't receive, or music choice channels. This should reduce the load on the Elite and you can see if that reduces or eliminates the stutter.

    I should have mentioned that the stutter happens even when ZERO tuners are recording.

    But I am curious how does one change the unused tuners to another channel?

    Tuners are always recording something (buffering live TV). While in live tv press right and choose one of the 3 circles to switch to that tuner. Then tune to a channel you don't receive. Repeat for each circle (tuner) except tune to a different channel you don't receive until all tuners are that way. Now try playing back a recording to see what happens. NOTE: Each tuner has to be on a different channel you don't receive in order for this to work since under normal conditions if you tune to a channel already being recorded it will just switch to that tuner.

    So if the tuners are "always recording", then is there really no difference between viewing live Tv and viewing a show recorded three days ago? If not, why do I NEVER see a single stutter when I'm on live Tv?

    I will try your test but it might not behave any different than what I am already doing - When I start to see stutter, if I dump to live Tv then go back and resume playing that show, the stutter is usually gone.

    Well it's actually additional load because not only is the unit recording 4 streams, but it's also playing back a 5th one in that scenario. For live TV it's back to 4 streams.

    It should not be stuttering even when the Premiere is reading/writing eight or nine streams. Five streams is certainly not an issue.

    I was having the exact same problem. I was getting stuttering intermittently. When I rewound it was not there. I thought the hard drive was going. Did a kickstart 54 test and it did not show anything. Support suggested remove ethernet (in my case) and remove the cablecard and just use the tivo to playback to try to eliminate sources. It still stuttered. I exchanged the box.

    One thing I did notice. I use pytivo and used it to "pull" a movie to the box. Just when the transfer was going to start. The new box stuttered for a second.

    I think that like others indicated that the processor cant handle the load. Especially with the HD interface which seems to really drain it.

    For a healthy unit yes. But here we are trying to reduce the stress on the unit to see if it helps in this case such that if it does then it would indicate a potential issue with the unit, perhaps a hard drive problem.

    I have owned a Premiere XL4 for about one year and also have Comcast CTV and a hard-wired ethernet connection.

    I get the occasional "stutter" which is clearly not a signal problem. I assume that it is, in fact, HDD-related but have not diagnosed the issue. At first I was concerned that it might be evidence of a significant defect, but the occurrence is rare enough that I have not pursued any remedies to date.

    I have found the easiest and most reliable cure is to hit pause and then (frame-by-frame) rewind a couple of times. When I resume play, the stutter is gone if it wasn't a signal issue. YMMV.

    Like the OP, I often get stuttering and pixelation on my Xl4 when playing back recorded shows, and never get it while watching live TV even though its basically the same process, just a few milliseconds after record rather than hours or days. It doesn't seem to matter if anything else is recording or not. I didn't see this with my 2 tuner Premiere.

    Recording is a pretty light process, just storing the bitstream to disk. Playback is where all the decoding, formatting, upscaling etc. happens. I also have the XL4 on a Gigabit switch with a 50/5 internet connection so thats not my issue.

    I would exchange the XL4 if you are getting stuttering and pixelation when playing back a recorded show. If either of my Elites were exhibiting that behavior I would be taking them to Best Buy to use the four year extended warranty I got on them.

    I've been noticing stuttering in my Premiere (2 tuner). I had upgraded the drive immediately to a WD Green WD20EARS after purchasing it and set the original drive aside. The stutter is present both live TV and in the recording. Happens every 30 seconds or so.

    I only use an antennae with this Tivo. Tomorrow I am having a cable card installed. So i decided to put the original drive back in so the pairing was done with that drive in place. I immediately noticed the stuttering disappeared while using the original drive.

    As a test today I cloned my WD20EARS to another WD20EARS (using a hardware cloner). Just put the new drive in and the stuttering is back. :(

    Not sure what that indicates. I don't believe both drives can be bad, but maybe that model drive is not recommended? (I had thought I had read it was ok....). I can't remember how I upgraded this the first go round (been awhile and the Tivo has not been used for 1yr+).

    Anyways, before Comcast arrives tomorrow, the original drive will go back in. Then i will just use JMFS to upgrade once again to a 2TB. Hopefully it works better this time. Perhaps I should pick a different model hard drive? Recommendations?

    Did you use wdidle to disable Intellipark on the WD20EARS? My preference for replacement drives in TiVo's have been WD's AV drives (WD20EURS now) and those come with Intellipark disabled.

    Absolutely NO pixellation here. I only have very intermittent stutter, more precisely it's like someone is pressing pause/play.... pause/play..... pause/play.... at different intervals.

    Honestly, I don't recall any more. I thought WDidle3 was to help with this drive not starting after (warm) reboot? I'll definitely look into it. (Mine doesn't exhibit that problem.)

    BTW, by "stutter" i mean pixelation.

    I may have been too pessimistic. It stuttered twice with the new drive immediately after starting (about 2 minutes apart), but I haven't noticed it since. :up:

    Greg,

    First thing I would do is pull the drive and check the state of wdidle to see if you have modified it from the default of 8 seconds. Not sure whether to recommend bumping it up to 300 or totally disabling it as some have reported issues with totally disabling it on the EARx models but I can tell you that it is totally disabled on the EURS AV models.

    I believe your memory of disabling wdlidle for boot issues was an issue about 2 years ago related to using WD green drives in S3's.

    I just got a new XL4 and mini combo. Haven't had TIVO in about eight years. Had a few premier at the PIL homes put in though.

    So, after three days of use, I am experiencing the stuttering on recorded playback. this is either with other shows being recorded, or not. (I know, somethings is ALWAYS being recorded)...it isn't THERE on the recording, since I can backup and replay and it doesn't repeat itself in the same place, but it happens again a bit latter.

    Why is this? What is the 54 reboot test and would that tell me if there are HD issues?

    should I just return this one to tivo and get a replacement?
