    I don't think "Remote Manufacturer Code" is the TV code you're looking for. I think it's just some code for who actually made the Tivo remote. My Roamio running Hydra has no such field, but has "Remote Type/Mode" instead and shows "SlidePro".

    Is this tv/dvd combo? If so try codes 0126 or 0142.

    What I meant was that your TV RF can't be programmed into your TiVo remote. For example, I have a new Samsung TV that came with an RF-only remote; my TiVo Slide and my Harmony remotes couldn't learn its IR commands nor control the TV by RF.

    The only thing that knows the TV code to IR translation is the remote; it would seriously complicate remote to add circuits and programming to upload the current code to the TiVo, and it would require a new remote to replace the existing ones, which wouldn't help OP at all. (As am aside, consider the fact that the RF reporting of the remote status in the current TiVo firmware is completely broken.)

    (Every time I set up a device that requires any significant configuration I create a Evernote entry and record things I might need to redo the configuration. I can tell you the codes I have programmed into my TiVo remotes for all the TVs I have owned since I bought my first TiVo. But I also take weekly automated backups of every computer I own onto a NAS server, so I might not be the typical user.)

    It's just a TV, not a combo.

    Thanks,

    @ej42137, I think we have our wires crossed. All we're talking about in this thread is send one value, the Tivo device setup code for IR control of the TV, i.e., 0008, via bluetooth to display on the info screen as another parameter like battery level, probably 2 bytes max. We're not talking about any RF control of anything at all.

    And consider this is just a fantasy. I don't expect Tivo to ever actually do this. But knowing what I know about the inner workings of remotes, it should be very simple. The setup code is typical stored in a fixed, 2-byte location in memory. Whatever status data strings the remote is sending today, those 2 bytes could be copied and appended. No new circuits, just a couple more lines of code.

    What I'm saying Dish does is transmit the IR codes (typically 30 bytes or so) from the box to the remote. Even $1 cable TV remotes have enough memory to store a couple hundred "custom" IR codes. I'm not suggesting Tivo do this at all. I'm just using it as an example to show that it's possible to send lots more data to/from a remote.

    That four digit code is programmed into the remote, not the TiVo. There is no facility to update the firmware of the remote to implement such a feature. If you think TiVo should have done it this way when they designed the RF remote, I think that's way low on the list of things TiVo should have done. I doubt they'd have gotten the programming right, since they can't even get the remote power level indicator to work.

    Consider that such a feature would only be useful to people with off-brand TVs. For most people, if they forgot what code they entered the list of codes they need to try is just the ones listed for their brand of TV.

    I don’t blame you.

    It would have been easy for TiVo to have had some sort of way to get codes off the remote via LED blinks or from an info screen through RF. I suspect they could probably add it to the info screen now if they cared to.

    Best,

    I am very disappointed in you. Did Columbus give up when he was bringing smallpox to the the New World?

    I’ll give LG a try, but I have my doubts the code will ever be known ;-)

    My Mini Vox has "Remote Control Firmware Update" as an option under "Remote Control Setup". When I search for this it does not come up in the entire history of this forum. Is this new in 21.8.3.RC2?

    I think that is correct. But it was the release before this that that whole section was introduced. But it doesn't do anything and seems to not function with some hardware.

    Interesting. So if they could get this update facility to actually work, the Mini Vox Remote could get updated with the ability to communicate whatever remote code it has set to the host TiVo where it could be reported.

    It's got me curious, but not enough to actually update the firmware on any of my remotes. They all are working right now, and I don't want to break them...LOL

    The other person that reported this said it doesn't do anything. I had one machine on Hydra for a while but I found it distasteful and so sent it back to TE3, therefore I have no first-hand experience in the matter.

    I came across this thread because I have a similar problem/desire as the OP. I recently purchased an RCA 19" "Travel" TV (model RT1971-AC). It was a "Black Friday" special sold by Stein Mart this past holiday season (2018). I have it connected to a Mini (TCDA93000, RF pre-VOX), and control the TV's power and volume/mute via the Mini's remote. I have tried countless codes, but none work. Via the search routine, I can eventually find it, but it's a PITA to repeat. Because I'm often intrigued by such problems (a flavor of insanity, I know), I took the time and effort to determine that the code resides approximately 366 "button pushes" into the search. Knowing that, I can at least speed-count up to close to 366 then go slow and stumble on the correct code.

    So I have 3 requests here:
    1) Would anyone happen to have also acquired that TV and know the code?
    2) Anyone have some thoughts on which (non-obvious) codes to try? The manual says the TV is made by Display-Vu Corp, an affiliate of Curtis Intl. (www.rcadisplayvu.com)
    3) Does knowing that it's 366 steps in help to determine the code? I don't suppose it's as simple as 999-366=0633 (or some other deterministic algorithm)?

    Thanks for any help this great community can provide.

    Recent RCA TV's have been using LG code or 128.

    Edmund - thx for the quick response, but unfortunately none of the LG or 0128 codes worked. I think the problem is this isn't a "recent" RCA TV, but rather either "new old stock" rebranded RCA, or a one-off production run of an old design specifically for the Xmas season. I guess I could open it up and see if I can find any other markings inside that might shed light on its genealogy.

    I had another somewhat off-the-wall idea. Has anyone ever considered creating a database of Tivo codes from the remote itself? My thinking is to walk through every code starting with 0001, program the remote, then capture the IR hex string produced by hitting the TV/Power button. That would be the basis of the database. Then if one had an unknown TV (like in my case), one could capture the IR hex string from the original remote (or a Tivo remote programmed through the search process), and do a reverse look-up in the database to find the matching string and thus reveal the corresponding Tivo code.

    Although certainly possible, I'm not proposing someone actually do all that by hand, but rather program something like a Raspberry Pi to do the work. LIRC can certainly handle all the IR work involved, but the challenge may be interfacing with the remote itself to logically "press the buttons" under control of the RPi to build the initial database. Seems like an interesting project for a retired EE. And of course, I always go by the motto "if it's worth doing, it's worth overdoing." :)

    Thoughts?

    It's probably not a realistic goal. Even if someone spent the months required to do it by hand or figure out a way to automate it, how would most people capture a code from their TV or AVR remote and be able to extract it into something like a Philips Pronto code to compare it to the resultant database?
