Remote won't stay in RF mode

    I've wondered sometimes just how the RF-capable remotes decide when to send RF versus IR or what color LED to flash. When sending to a TV or AVR, presumably they just send IR. But when sending to a TiVo, do they detect some continuous RF beacon from the box and send RF only if it's present? Or do they always send both and then flash the right color LED only if there is an RF handshake from the box? Or what?

    Some posts in this thread have caused me to wonder recently if sending both RF and IR commands simultaneously to a TiVo could in some circumstances cause the box to recognize and act upon both signals instead of ignoring the redundant IR signal like it's presumably supposed to do. This could be the result of some sort of timing problem.

    My 4-tuner Roamio (used only for OTA) has on at least one occasion doubled presses of the Live TV button when cycling past only one of the four tuners, refusing to stop on only that tuner each time around. That surely can't have been a coincidence caused by hardware "contact bounce" or whatever. I wonder if a bit more code has to execute when cycling from tuner 3 back to tuner 0, with the extra millisecond or two causing what should be seen as a duplicate IR code to be seen instead as independent from the RF code which it should have matched, or something like that. Food for thought.

    It has merit since my basic Roamio can not receive IR codes. So when a command fails, I wait a few seconds and try it again. Sometime I look at the remote and see a red LED. Sometimes not, so I wait.

    Ok, this is strange. I have found that when my Roamio remote, set in RF mode, drops to IR mode, that if I cover the front with my hand the RF mode returns. The front of my Roamio is blocked so IR commands can never reach the box. It works every time.

    I'll play with that a bit, although it's not a solution because most people (including me) use the IR part for power, volume, and mute functions. And I shouldn't have to cover the front of the remote on a system that, all told, cost about a thousand dollars in order to have it do stuff reliably.

    The Roamio and Minis definitely have remote problems, have had them from the beginning. I have a Pro and three Minis, and all exhibit to some extent the same stupid behavior detailed in this (and other) threads, although the Minis are worse here. TiVo's 'solution' of resetting and re-pairing the remote works for, at most, a few days, after which it reverts to being deranged again.

    Since it's the main interface to the box, and a lot of the user experience derives from how responsive the system is to commands, it astonishes me that TiVo had done nothing but stonewall users while incapable of solving this incredibly frustrating issue for many of its customers.

    I mean seriously, what the hell, TiVo?

    True, I control my AVR and TV with the remote, and it doesn't ALWAYS drop into IR mode, but this is my second remote. On a different Roamio the remote seems to stutter a lot. I never have problems on the Mini.

    I doubt covering it is doing anything. When mine drops to IR mode, it only does IR for a second before going back to RF on its own. Covering it is probably just coincidental to it working again.

    I've found my remote (Roamio basic) starts sporadically reverting to IR mode after any TiVo restart. For example I had to do a global reset/re-pair after getting the RC10a update recently.

    The problem is so weird: It will RF from 25 ft away around a corner but will fall back to IR from only 8 ft away if the remote is pointed at certain angles, for example 45 degrees off of pointing right at the TiVo. Fortunately I get periods of many weeks when it stays RF.

    Try making IR impossible. I often wonder how many people never notice the IR mode switch. I only noticed when I blocked the front of my Roamio since I have a Premiere in close proximity. It's on channel 2 and has its own remote.

    Wonder what could explain this? How could the remote know you have the TIVo IR receiver blocked? I assume it receives RF signals back from the TiVo but that doesn't lead me to any idea of how to explain this behavior.

    I have no clue. I only saw this behavior by accident. It doesn't have to be your hand either. Maybe the reduction of the RF signal level has some affect. If so, I'm going to try to add some rf blockage to my wooden block.

    I've had this same exact behaviour since day one of owning my Roamio...yet another issue that TiVo has never and will never address.

    I just placed a dual foil backed foam insulation in front of my basic Roamio, behind the 1/4" piece of wood already there. RF still works. When if fails I'll leave a post.

    I don't think that will work for me, I need IR to control my TV and RF to control my TiVo behind the wall.

    So do I. I never suggested to permanently block the remote. I just noticed when I covered the front with my hand the LED went back to amber. Could it be a coincidence? Perhaps. I'm testing an RF proof block in front of the Roamio. So far it's working. My Roamio is only 10' from my remote, so maybe the RF signal is too strong. And I have nothing better to do today. It's raining. :)

    Just measured: it's only 6' from the Roamio.

    Before I let this thread go back to low priority, I need to add new information.

    If you bring up the guide, then hit right, you can watch the remote's LED. Just before it drops from RF to IR, the color goes sort of half red and half amber. If you stop there and wait a few seconds, it stays amber and in RF mode. Hit right quickly and the LED goes red. Put your hand over the front of the remote and it will drop back to RF. Four levels of shielding reduce the issue, but don't stop it. Ok, back to sleep. :)
