    Unfortunately, I don't believe that the lineup would survive a carrier frequency update.

    Well, I'm DEFINITELY interested in it, and would even be VERY likely to donate some money to you if it really worked well.. But shipping drives and/or images back and forth makes me very wary. This seems morally to me to be very close to copyright infringement. If there's a way I could perform this on my own Tivo, I would. (I guess some day I'll have to go search for the other scripts someone mentions above... This sounds VERY similar to the old 'hack' about "cable + satellite".. which I referred to in the gigantic clear QAM a few years ago.)

    A truncated backup or a full backup?

    truncated. that's why you might lose your recordings.

    I'm glad to report that this method does indeed work. I provided Stubby with the requirements listed above (check Saxion's 1st post) and I received a modified image that works exactly as advertised. Not having guide data for my clear QAM HD channels was a deal-breaker for me, and I was about ready to return the Tivo, so thank you very much Stubby.

    You can get it here, don't even need to mod your TIVO:

    http://************.com/forum/showthread.php?t=58822

    If someone wants to apply it then do an ISO of their drive and post it up on the net it will be just as easy to install as this one, and it doesn't suffer the problems this one does.

    Your last post in that thread says "Anyone try this on a non-hacked box yet?", so how can you claim that you don't need to mod your Tivo?

    Exactly and how do you even run a TCL script on a non-hacked box?

    You can't run it on an unhacked tivo. You can pull the drive on an unhacked tivo, move it to a hacked tivo to run the script, then move it back into the unhacked tivo. The channel lineup changes should be preserved and the unhacked tivo will now have clear QAM channel guide data. This is the service that stubby was offering.

    The alternative would be a program on the PC side that could make these MFS modifications. With such a program, people could do this themselves without a hacked tivo. This is non trivial, but possible. It's not trivial because the publicly available tools that grok MFS on the PC side (mfs-utils and mfstools) are primitive and don't have full write access to the data structures.

    I summarized things over here and stubby agreed with the summary.

    Just to close out this thread,

    JamieP has again hit the nail on the head with the technical assessment. With two cases of success, I'm comfortable saying that this process works and the only remaining question is for how long (with the final answer ultimately varying upon individual details).

    Judging the relative demand for QAM Mapping, I've no plans to offer a paid service and due to time constraints, I'll no longer be offering it free. Folks wishing to explore this on their own can follow JamieP's outline and utilize the newly posted script on the "other forum".

    In case anyone's wondering, the custom lineup still works perfectly. I think at this point the only foreseeable problem would be my cable company changing their lineup... at which time I will need to brush up on my soldering skills.

    Same here; custom lineup still going strong. It has survived multiple TiVo firmware updates, and some OTA channel list changes due to the DTV transition. Thanks again stubby, you're my hero. :)

    We all don't wish to get involved with imaging HDD upgrades. Companies which offer preconfigured HDD's or other TiVo modifications definitely have a place within the TiVo Community as long as TiVo Service itself isn't compromised. Tivo itself unofficially encourages this.

    I have no interest in making such modifications myself but would certainly consider paying for them when practical, durable solutions become available at a reasonable price from a reputable source.

    Why is this thread ending with the thought that a good intention killed a goose that laid golden eggs?

    An amusing right-wing version of Aesop's goose fable:

    I was being a jerk. I had the idea that he was trying to hide something from us.

    Now that we all know how the hack works I support the OP in charging others for the service who are unable to hack themselves.

    Land of...
    The more
    TiVo, Inc. resists providing program data for cable channels I pay for and receieve the closer I get to paying someone for this service. I really don't care to learn and perfect the skills to hack TiVo myself. Wondering if this works for PSIP mapped cable from EvilCast? While EvilCast does move the mapped channels about some the PSIP should remain static or the long haul requiring minimal updating and make this an even more attractive option...

    I'm not sure what your point is. Tivo provides guide data for digital stations that are mapped via cable cards. Customers that don't want to use cable cards, or are in one of the few systems that don't offer cable cards to any customers (all channels are in the clear), should return tivo under the 30 day return window.

    Customers that don't receive encrypted stations and don't want to pay cable card fees are free hack, or pay someone else to hack. Tivo has made it clear QAM mapping isn't on the "to do list" of new features.

    I have a gut feeling TiVo is working on this in the Series 4 model and may provide some clear QAM mapping there since they will have an interactive TiVo and presumably tru2way APIs to get the mapping in some form with out relying on cable card to be sent the mapping blindly.


    PS - for people not familiar with the terms here
    It would be more correct to say the script needs to be run on a modified TiVo DVR (modded) which is a not trivial replacement of a chip on the mainboard.

    A hacked TiVo implies changes to the hard drive files - which can happen once the chip is swapped out.

    the people posting this hack sound like they know what they are doing just fine - I just wanted to clarify for someone new to this stuff

    I know this is a a long shot given the age of this post but does anyone have any information about this approach? I have searched all over and I am unable to find anything. I am trying to do this with an S3 and fios where I get clear QAM as part of my subscription. Thanks in advance to anyone that can help.
