    I would definitely return a TiVo within the 30 day return period, if TiVo cannot get it working perfectly for you within the first couple of weeks. You can try again later, if you wish, as long as TiVo is willing to honor the 30 day return period, but there is no reason to take a risk given that CableCARD technology is so intrinsically unreliable.

    Bicker,
    Thanks for the advise. Not being a constant reader of these forums does Tivo have a known issue with partial recording. I only got 18 minutes of the Amazing Race last night. I didn't buy my Tivo from TIVO but BBuy so returning it will be easy but want to make sure not to pass the return period. I have asked my cable company who has a TIVO HD unit to start doing alot of recordings and let me know.
    Thanks for the advice as much as I like the unit I need it reliable.

    I just wanted to chime in with a problem also, I have 3 tivo HD's that use an M card and I record tons of stuff on each and I have never had one single partial recording, I upgraded all 3 with 1 tb drives. I bought a used tivo hd(got a good deal on it) upgraded the HD with a TB drive and sold it on ebay, the guy had nothing but problems with it, rebooting and getting partial recordings, so I let him return it for a refund, I thought maybe it was something easy to fix. Well I am getting the same reboots and partial recordings, I even put in the original hd and still the same thing, I even bought instant cake and put a fresh image on it thinking that maybe the original image was corrupt, still no go, still get partial recordings while my other 3 boxes work perfect, so I guess some boxes just might be bad no matter what we try.

    It depends on who you ask. CableCARD technology, itself, is very unreliable, IMHO, and TiVo's implementation of CableCARD technology is very sensitive to imperfections -- that's not the same thing as a "known issue": If everything in the chain, from the service provider, through the coax, through splitters and such, are all within tight tolerances, then it will (almost surely) work. If something along the way is a bit off-center, then there is a chance that that will cause problems. TiVo would say that the service provider or you should fix the part of the chain that isn't perfect. The service provider and perhaps you would say that TiVo should make their implementation less sensitive to imperfections. It's a matter of perspective and opinion, not a matter of a "known issue".

    Just for clarification: Is this with or without CableCARDs? If you can, I would test it just OTA.

    t.

    it is with cable cards, I am lucky that our cable comp doesn't pair the cards to the tivos and I can move them around. I haven't tried it with just analog just yet

    Hey all,

    I have just bought my TIVO DVR in Brisbane, Aust. TIVO has recently been launched here. I have having the rebooting problems all the time.

    Has anyone figured a fix for these problems yet?

    Thanks,

    Dan

    I believe I know what causes this. You should also notice an occasional gray/black screen with a Tivo banner message stating something like "no channel information available", or a stuck gray screen (if you change the channel the rest are fine). Also, both tuners will reset to the same channel (if tuner 0 was on channel 2 and tuner 1 was on channel 52, after a reset both tuners will be on channel 52). I believe a major cause for this is an incorrect firmware version in the cable company's m-card. I believe the Motorola M-card needs firmware version 2.65 and just version 2.01,--,3.25 will not work.

    Still waiting on my Firmware for SA M-Card. Anyone know what the correct one to get is? I am not a Cox Cable but a new startup company so don't know if they are the same for all companys using SA cards.

    Thanks,

    To second Hal's findings... this was exactly the issue I was running into with my partial recording issue. The Motorola M-Cards I'd received from my local Comcast office were:

    FW Version: 02.01, -.-,03.25
    HW Version: 0469927002

    I tried all sorts of things to try to pinpoint the cause... exhanged the Tivo HD, exchanged M-Cards, had Comcast check my signal quality/drop (test results were excellent), tried in-line attenuators in case the issue was related to a signal that was too "hot". In all cases the problem (frequent partial recordings, and occasional short-term loss of video/audio... with a Tivo banner status indicating "no channel information" until the picture returned in < 60 seconds) the problem remained.

    It wasn't until I stumbled on Hal's thread in the tivo.com forums that I realized someone else was seeing exactly the same symptoms I was. He had also noticed that, after the periodic loss of video/audio, the M-Card tuner's were both reset to the channel that Tuner 0 had been on.

    My local Comcast office is unable to find me an M-Card with 02.65 firmware (all those issued... and I've tried 3 during this process) were 02.01. So, I've resorted to using two S-Cards. It's been 3+ days and my parial recording issues do seem to have been resolved.

    Do you have a source for this piece of advice? I haven't seen any reports here suggesting that there are any known problems w/ the various versions of the motorola firmware.

    In the process of troubleshooting this I'd called Tivo support, and their rep found a tech note indicating loss of authorization issues with 2.01 of the Motorola M-Card. The note indicated that the firmware should be updated to the "latest" version. The tech even mentioned 2.65 specifically.

    I actually called Tivo support back this morning to see if I could get more specifics on the issue and the tech note... and to see if there would be some way they could publish the information to their site... If I'd known there were possible issues with 2.01 I might have been able to avoid some wasted time and money. To summarize the outcome of today's support call:

    * Per the rep, Motorola 02.01 firmware M-Card's are known to have issues, and upgrading to the current version is the way to go if you can.

    * The tech note isn't available, and they don't plan on publishing it due to concern that people might mis-interpret the information and jump to the wrong conclusion (incorrectly assume their issue is caused by this problem). The impression I got was that they would prefer to keep the published troubleshooting data very simple (without getting into specific firmware versions), and let phone support folks drill down to the right conclusion.

    * The rep indicated that not all 2.01 M-Card users are experiencing this issue. The theory suggested was that there are actually sub-versions of the firmware that are not being exposed in the FW strings... The rep told me it was common for the industry to roll sub versions if a given numeric version number, but that these sub-versions were not reported in the version ID string I see. This sounds odd to me, but what do I know.

    * The rep indicated that the number of people experiencing this particular set of 2.01 related issues was actually quite small.



    What's actually the true root cause of this problem I don't know. Are there really variations of 2.01 out there... I don't know.

    All I know is that I experienced the following issue across multiple Tivo HD units, and two locally issued Motorola 2.01 FW M-Cards:

    1) Fairly frequent (daily typically) partial recordings where the a portion of the tail end of a show would not be recorded. The recorded show would be cut short.

    2) While watching Live TV the video/audio would go black, the Tivo Channel banner would pop up telling me that there was no channel information, and about 60 seconds later the video/audio would return allong with an updated Tivo Channel banner with the program information refreshed. In the process both Tuners were re-tuned to the channel Tuner 0 had been on. Not a reboot... but the tuner's were being re-tuned/reset.

    I concluded that this intermittent Tuner reset (2) was likely to be the cause of my partial recordings (1).

    Replacing the M-Card with two Motorola S-Cards does appear to have fixed the issue. In 4+ days I've seen no sign of either 1 or 2.

    Hope this helps.

    I see this exact same problem at least a few times a month, but it appears that I have the "good" firmware version of the M-Card.

    CableCARD Status
    Manufacturer: Motorola
    FW Version: 02.65, 02.01, 03.25
    HW Version: 0469927002

    Except when my channel goes out and the no channel info banner comes up, the channel is typically tuned back within 5-10 seconds. Both tuners are then tuned to the current channel and recordings stop (partial). It seems to have happened on both SD and HD channels.

    So perhaps the problem is not so severe in my case, but it still exists with the firmware I have.

    I have Comcast service in Houston, TX

    Strange development.

    I guess I'll just stick with the two Motorola S-Cards, and hope someone at Tivo gets to the bottom of this.

    This is a real problem, but it seems that M-Card FW 2.65 may not be the solution.

    I urge anyone having these specific symptoms to contact Tivo support and let them know about their setup.

    Hopefully this will get some support/development attention if enough people call in the issue.

    So this thread has been running for almost 2 years and nobody has an answer? I'm running a TivoHD and recently switched from Charter to Time Warner. Two months after switching to TW I started having the "Partial" recording problem with shows cutting off at different times (some at only 0:06. Some at 0:20ish). It is VERY frustrating!

    I'm running on a Tivo 500GB external HD.

    Does anyone have any fix other than to switch the cable cards?

    Just thought I'd bump this thread since I just started having this problem this morning and no solution was posted.

    I have HD Tivo with Time Warner Cable. Everything was fine for almost 2 years, then this morning I lost every channel except for the unencrypted local channels. I have an M card identical to spaceboytom's:

    CableCARD Status
    Manufacturer: Motorola
    FW Version: 02.65, 02.01, 03.25
    HW Version: 0469927002

    My encrypted channels show up as Auth:CAD

    Does anyone know what CAD means here?

    My problems went away when Comcast moved off the Motorola cards to the Scientific Atlanta cards.
